Pro 2:10-11, 22:18 | MHC | STEP | The Benefits Conferred by Wisdom. 10 When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul; 11 Discretion shall preserve thee, understanding shall keep thee: 12 To deliver thee from the way of the evil man, from the man that speaketh froward things; 13 Who leave the paths of uprightness, to walk in the ways of darkness; 14 Who rejoice to do evil, and delight in the frowardness of the wicked; 15 Whose ways are crooked, and they froward in their paths: 16 To deliver thee from the strange woman, even from the stranger which flattereth with her words; 17 Which forsaketh the guide of her youth, and forgetteth the covenant of her God. 18 For her house inclineth unto death, and her paths unto the dead. 19 None that go unto her return again, neither take they hold of the paths of life. 20 That thou mayest walk in the way of good men, and keep the paths of the righteous. 21 For the upright shall dwell in the land, and the perfect shall remain in it. 22 But the wicked shall be cut off from the earth, and the transgressors shall be rooted out of it. The scope of these verses is to show, 1. What great advantage true wisdom will be of to us; it will keep us from the paths of sin, which lead to ruin, and will therein do us a greater kindness than if it enriched us with all the wealth of the world. 2. What good use we should make of the wisdom God gives us; we must use it for our own guidance in the paths of virtue, and for the arming of us against temptations of every kind. 3. By what rules we may try ourselves whether we have this wisdom or no. This tree will be known by its fruits; if we be truly wise, it will appear by our care to avoid all evil company and evil practices. This wisdom will be of use to us, I. For our preservation from evil, from the evil of sin, and, consequently, from the evil of trouble that attends it. 1. In general ( ), "When wisdom has entire possession of thee, it will keep thee. " And when has it an entire possession of us? (1.) When it has dominion over us. When it not only fills the head with notions, but enters into the heart and has a commanding power and influence upon that,--when it is upon the throne there, and gives law to the affections and passions,--when it enters into the heart as the leaven into the dough, to diffuse its relish there, and to change it into its own image--then it is likely to do us good. (2.) When we have delight in it, when knowledge becomes pleasant to the soul: "When thou beginnest to relish it as the most agreeable entertainment, and art subject to its rules, of choice, and with satisfaction,--when thou callest the practice of virtue, not a slavery and a task, but liberty and pleasure, and a life of serious godliness the most comfortable life a man can live in this world,--then thou wilt find the benefit of it." Though its restraints should be in some respects unpleasant to the body, yet even those must be pleasant to the soul. When it has come to this, with us, discretion shall preserve us and keep us. God keeps the way of his saints ( ), by giving them discretion to keep out of harm's way, to keep themselves that the wicked one touch them not. Note, A principle of grace reigning in the heart will be a powerful preservative both against corruptions within and temptations without, . 2. More particularly, wisdom will preserve us, (1.) From men of corrupt principles, atheistical profane men, who make it their business to debauch young men's judgments, and instil into their minds prejudices against religion and arguments for vice: "It will deliver thee from the way of the evil man ( ), and a blessed deliverance it will be, as from the very jaws of death, from the way in which he walks, and in which he would persuade thee to walk." The enemy is spoken of as one ( ), an evil man, but afterwards as many ( ); there is a club, a gang of them, that are in confederacy against religion, and join hand in hand for the support of the devil's kingdom and the interests of it. [1.] They have a spirit of contradiction to that which is good: They speak froward things; they say all they can against religion, both to show their own enmity to it and to dissuade others from it. They are advocates for Satan; they plead for Baal, and pervert the right ways of the Lord. How peevishly will profane wits argue for sin, and with what frowardness will they carp at the word of God! Wisdom will keep us either from conversing with such men or at least from being ensnared by them. [2.] They are themselves apostates from that which is good, and such are commonly the most malicious and dangerous enemies religion has, witness Julian ( ): They leave the paths of uprightness, which they were trained up in and had set out in, shake off the influences of their education, and break off the thread of their hopeful beginnings, to walk in the ways of darkness, in those wicked ways which hate the light, in which men are led blindfold by ignorance and error, and which lead men into utter darkness. The ways of sin are ways of darkness, uncomfortable and unsafe; what fools are those that leave the plain, pleasant, lightsome paths of uprightness, to walk in those ways! . [3.] They take a pleasure in sin, both in committing it themselves and in seeing others commit it ( ): They rejoice in an opportunity to do evil, and in the accomplishment and success of any wicked project. It is sport to fools to do mischief; nor is any sight more grateful to them than to see the frowardness of the wicked, to see those that are hopeful drawn into the ways of sin, and then to see them hardened and confirmed in those ways. They are pleased if they can discern that the devil's kingdom gets ground (see ), such a height of impiety have they arrived at. [4.] They are resolute in sin ( ): Their ways are crooked, a great many windings and turnings to escape the pursuit of their convictions and break the force of them; some sly excuse, some subtle evasion or other, their deceitful hearts furnish them with, for the strengthening of their hands in their wickedness; and in the crooked mazes of that labyrinth they secure themselves from the arrests of God's word and their own consciences; for they are froward in their paths, that is, they are resolved to go on in them, whatever is said against it. Every wise man will shun the company of such as these. (2.) From women of corrupt practices. The former lead to spiritual wickednesses, the lusts of the unsanctified mind; these lead to fleshly lusts, which defile the body, that living temple, but withal war against the soul. The adulteress is here called the strange woman, because no man that has any wisdom or goodness in him will have any acquaintance with her; she is to be shunned by every Israelite as if she were a heathen, and a stranger to that sacred commonwealth. A strange woman indeed! utterly estranged from all principles of reason, virtue, and honour. It is a great mercy to be delivered from the allurements of the adulteress, considering, [1.] How false she is. Who will have any dealings with those that are made up of treachery? She is a strange woman; for, First, She is false to him whom she entices. She speaks fair, tells him how much she admires him above any man, and what a kindness she has for him; but she flatters with her words; she has no true affection for him, nor any desire of his welfare, any more than Delilah had of Samson's. All she designs is to pick his pocket and gratify a base lust of her own. Secondly, She is false to her husband, and violates the sacred obligation she lies under to him. He was the guide of her youth; by marrying him she chose him to be so, and submitted herself to his guidance, with a promise to attend him only, and forsake all others. But she has forsaken him, and therefore it cannot be thought that she should be faithful to any one else; and whoever entertains her is partaker with her in her falsehood. Thirdly, She is false to God himself: She forgets the covenant of her God, the marriage-covenant ( ), to which God is not only a witness, but a party, for, he having instituted the ordinance, both sides vow to him to be true to each other. It is not her husband only that she sins against, but her God, who will judge whoremongers and adulterers because they despise the oath and break the covenant, . [2.] How fatal it will prove to those that fall in league with her, . Let the sufferings of others be our warnings. Take heed of the sin of whoredom; for, First, The ruin of those who are guilty of it is certain and unavoidable, if they do not repent. It is a sin that has a direct tendency to the killing of the soul, the extinguishing of all good affections and dispositions in it, and the exposing of it to the wrath and curse of God and the sword of his justice. Those that live in forbidden pleasures are dead while they live. Let discretion preserve every man, not only from the evil woman, but from the evil house, for the house inclines to death; it is in the road that leads directly to eternal death; and her paths unto Rephaim, to the giants (so some read it), the sinners of the old world, who, living in luxury and excess of riot, were cut down out of time, and their foundation was overthrown with a flood. Our Lord Jesus deters us from sinful pleasures with the consideration of everlasting torments which follow them. Where the worm dies not, nor is the fire quenched. See . Secondly, Their repentance and recovery are extremely hazardous: None, or next to none, that go unto her, return again. It is very rare that any who are caught in this snare of the devil recover themselves, so much is the heart hardened, and the mind blinded, by the deceitfulness of this sin. Having once lost their hold of the paths of life, they know not how to take hold of them again, but are perfectly besotted and bewitched with those base lusts. Many learned interpreters think that this caution against the strange woman, besides the literal sense, is to be understood figuratively, as a caution, 1. Against idolatry, which is spiritual whoredom. Wisdom will keep thee from all familiarity with the worshippers of images, and all inclination to join with them, which had for many ages been of such pernicious consequence to Israel and proved so to Solomon himself. 2. Against the debauching of the intellectual powers and faculties of the soul by the lusts and appetites of the body. Wisdom will keep thee from being captivated by the carnal mind, and from subjecting the spirit to the dominion of the flesh, that notorious adulteress which forsakes its guide, violates the covenant of our God, which inclines to death, and which, when it has got an undisturbed dominion, makes the case of the soul desperate. II. This wisdom will be of use to guide and direct us in that which is good ( ): That thou mayest walk in the way of good men. We must avoid the way of the evil man, and the strange woman, in order that we may walk in good ways; we must cease to do evil, in order that we may learn to do well. Note, 1. There is a way which is peculiarly the way of good men, the way in which good men, as such, and as far as they have really been such, have always walked. 2. It will be our wisdom to walk in that way, to ask for the good old way and walk therein, . And we must not only walk in that way awhile, but we must keep it, keep in it, and never turn aside out of it: The paths of the righteous are the paths of life, which all that are wise, having taken hold of, will keep their hold of. "That thou mayest imitate those excellent persons, the patriarchs and prophets (so bishop Patrick paraphrases it), and be preserved in the paths of those righteous men who followed after them." We must not only choose our way in general by the good examples of the saints, but must also take directions from them in the choice of our particular paths; observe the track, and go forth by the footsteps of the flock. Two reasons are here given why we should thus choose:-- (1.) Because men's integrity will be their establishment, . It will be the establishment, [1.] Of their persons: The upright shall dwell in the land, peaceably and quietly, as long as they live; and their uprightness will contribute to it, as it settles their minds, guides their counsels, gains them the good-will of their neighbours, and entitles them to God's special favour. [2.] Of their families: The perfect, in their posterity, shall remain in it. They shall dwell and remain for ever in the heavenly Canaan, of which the earthly one was but a type. (2.) Because men's iniquity will be their destruction, . See what becomes of the wicked, who choose the way of the evil man; they shall be cut off, not only from heaven hereafter and all hopes of that, but from the earth now, on which they set their affections, and in which they lay up their treasure. They think to take root in it, but they and their families shall be rooted out of it, in judgment to them, but in mercy to the earth. There is a day coming which shall leave them neither root nor branch, . Let that wisdom then enter into our hearts, and be pleasant to our souls, which will keep us out of a way that will end thus.

Proverbs 2:10-11

10 When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul; 11 Discretion shall preserve thee, understanding shall keep thee: 12 To deliver thee from the way of the evil man, from the man that speaketh froward things; 13 Who leave the paths of uprightness, to walk in the ways of darkness; 14 Who rejoice to do evil, and delight in the frowardness of the wicked; 15 Whose ways are crooked, and they froward in their paths: 16 To deliver thee from the strange woman, even from the stranger which flattereth with her words; 17 Which forsaketh the guide of her youth, and forgetteth the covenant of her God. 18 For her house inclineth unto death, and her paths unto the dead. 19 None that go unto her return again, neither take they hold of the paths of life. 20 That thou mayest walk in the way of good men, and keep the paths of the righteous. 21 For the upright shall dwell in the land, and the perfect shall remain in it. 22 But the wicked shall be cut off from the earth, and the transgressors shall be rooted out of it.

The scope of these verses is to show, 1. What great advantage true wisdom will be of to us; it will keep us from the paths of sin, which lead to ruin, and will therein do us a greater kindness than if it enriched us with all the wealth of the world. 2. What good use we should make of the wisdom God gives us; we must use it for our own guidance in the paths of virtue, and for the arming of us against temptations of every kind. 3. By what rules we may try ourselves whether we have this wisdom or no. This tree will be known by its fruits; if we be truly wise, it will appear by our care to avoid all evil company and evil practices.

This wisdom will be of use to us,

I. For our preservation from evil, from the evil of sin, and, consequently, from the evil of trouble that attends it.

1. In general (v. 10, 11), "When wisdom has entire possession of thee, it will keep thee." And when has it an entire possession of us? (1.) When it has dominion over us. When it not only fills the head with notions, but enters into the heart and has a commanding power and influence upon that,--when it is upon the throne there, and gives law to the affections and passions,--when it enters into the heart as the leaven into the dough, to diffuse its relish there, and to change it into its own image--then it is likely to do us good. (2.) When we have delight in it, when knowledge becomes pleasant to the soul: "When thou beginnest to relish it as the most agreeable entertainment, and art subject to its rules, of choice, and with satisfaction,--when thou callest the practice of virtue, not a slavery and a task, but liberty and pleasure, and a life of serious godliness the most comfortable life a man can live in this world,--then thou wilt find the benefit of it." Though its restraints should be in some respects unpleasant to the body, yet even those must be pleasant to the soul. When it has come to this, with us, discretion shall preserve us and keep us. God keeps the way of his saints (v. 8), by giving them discretion to keep out of harm's way, to keep themselves that the wicked one touch them not. Note, A principle of grace reigning in the heart will be a powerful preservative both against corruptions within and temptations without, Eccl. ix. 16, 18.

2. More particularly, wisdom will preserve us,

(1.) From men of corrupt principles, atheistical profane men, who make it their business to debauch young men's judgments, and instil into their minds prejudices against religion and arguments for vice: "It will deliver thee from the way of the evil man (v. 12), and a blessed deliverance it will be, as from the very jaws of death, from the way in which he walks, and in which he would persuade thee to walk." The enemy is spoken of as one (v. 12), an evil man, but afterwards as many (v. 13); there is a club, a gang of them, that are in confederacy against religion, and join hand in hand for the support of the devil's kingdom and the interests of it. [1.] They have a spirit of contradiction to that which is good: They speak froward things; they say all they can against religion, both to show their own enmity to it and to dissuade others from it. They are advocates for Satan; they plead for Baal, and pervert the right ways of the Lord. How peevishly will profane wits argue for sin, and with what frowardness will they carp at the word of God! Wisdom will keep us either from conversing with such men or at least from being ensnared by them. [2.] They are themselves apostates from that which is good, and such are commonly the most malicious and dangerous enemies religion has, witness Julian (v. 13): They leave the paths of uprightness, which they were trained up in and had set out in, shake off the influences of their education, and break off the thread of their hopeful beginnings, to walk in the ways of darkness, in those wicked ways which hate the light, in which men are led blindfold by ignorance and error, and which lead men into utter darkness. The ways of sin are ways of darkness, uncomfortable and unsafe; what fools are those that leave the plain, pleasant, lightsome paths of uprightness, to walk in those ways! Ps. lxxxii. 5; 1 John ii. 11. [3.] They take a pleasure in sin, both in committing it themselves and in seeing others commit it (v. 14): They rejoice in an opportunity to do evil, and in the accomplishment and success of any wicked project. It is sport to fools to do mischief; nor is any sight more grateful to them than to see the frowardness of the wicked, to see those that are hopeful drawn into the ways of sin, and then to see them hardened and confirmed in those ways. They are pleased if they can discern that the devil's kingdom gets ground (see Rom. i. 32), such a height of impiety have they arrived at. [4.] They are resolute in sin (v. 15): Their ways are crooked, a great many windings and turnings to escape the pursuit of their convictions and break the force of them; some sly excuse, some subtle evasion or other, their deceitful hearts furnish them with, for the strengthening of their hands in their wickedness; and in the crooked mazes of that labyrinth they secure themselves from the arrests of God's word and their own consciences; for they are froward in their paths, that is, they are resolved to go on in them, whatever is said against it. Every wise man will shun the company of such as these.

(2.) From women of corrupt practices. The former lead to spiritual wickednesses, the lusts of the unsanctified mind; these lead to fleshly lusts, which defile the body, that living temple, but withal war against the soul. The adulteress is here called the strange woman, because no man that has any wisdom or goodness in him will have any acquaintance with her; she is to be shunned by every Israelite as if she were a heathen, and a stranger to that sacred commonwealth. A strange woman indeed! utterly estranged from all principles of reason, virtue, and honour. It is a great mercy to be delivered from the allurements of the adulteress, considering, [1.] How false she is. Who will have any dealings with those that are made up of treachery? She is a strange woman; for, First, She is false to him whom she entices.

But she has forsaken him, and therefore it cannot be thought that she should be faithful to any one else; and whoever entertains her is partaker with her in her falsehood. Thirdly, She is false to God himself: She forgets the covenant of her God, the marriage-covenant (v. 17), to which God is not only a witness, but a party, for, he having instituted the ordinance, both sides vow to him to be true to each other. It is not her husband only that she sins against, but her God, who will judge whoremongers and adulterers because they despise the oath and break the covenant, Ezek. xvii. 18; Mal. ii. 14. [2.] How fatal it will prove to those that fall in league with her, v. 18, 19. Let the sufferings of others be our warnings. Take heed of the sin of whoredom; for, First, The ruin of those who are guilty of it is certain and unavoidable, if they do not repent. It is a sin that has a direct tendency to the killing of the soul, the extinguishing of all good affections and dispositions in it, and the exposing of it to the wrath and curse of God and the sword of his justice. Those that live in forbidden pleasures are dead while they live. Let discretion preserve every man, not only from the evil woman, but from the evil house, for the house inclines to death; it is in the road that leads directly to eternal death; and her paths unto Rephaim, to the giants (so some read it), the sinners of the old world, who, living in luxury and excess of riot, were cut down out of time, and their foundation was overthrown with a flood. Our Lord Jesus deters us from sinful pleasures with the consideration of everlasting torments which follow them. Where the worm dies not, nor is the fire quenched. See Matt. v. 28, 29. Secondly, Their repentance and recovery are extremely hazardous: None, or next to none, that go unto her, return again. It is very rare that any who are caught in this snare of the devil recover themselves, so much is the heart hardened, and the mind blinded, by the deceitfulness of this sin. Having once lost their hold of the paths of life, they know not how to take hold of them again, but are perfectly besotted and bewitched with those base lusts. Many learned interpreters think that this caution against the strange woman, besides the literal sense, is to be understood figuratively, as a caution, 1. Against idolatry, which is spiritual whoredom. Wisdom will keep thee from all familiarity with the worshippers of images, and all inclination to join with them, which had for many ages been of such pernicious consequence to Israel and proved so to Solomon himself. 2. Against the debauching of the intellectual powers and faculties of the soul by the lusts and appetites of the body. Wisdom will keep thee from being captivated by the carnal mind, and from subjecting the spirit to the dominion of the flesh, that notorious adulteress which forsakes its guide, violates the covenant of our God, which inclines to death, and which, when it has got an undisturbed dominion, makes the case of the soul desperate.

II. This wisdom will be of use to guide and direct us in that which is good (v. 20): That thou mayest walk in the way of good men. We must avoid the way of the evil man, and the strange woman, in order that we may walk in good ways; we must cease to do evil, in order that we may learn to do well. Note, 1. There is a way which is peculiarly the way of good men, the way in which good men, as such, and as far as they have really been such, have always walked. 2. It will be our wisdom to walk in that way, to ask for the good old way and walk therein, Jer. vi. 16; Heb. vi. 12; xii. 1. And we must not only walk in that way awhile, but we must keep it, keep in it, and never turn aside out of it: The paths of the righteous are the paths of life, which all that are wise, having taken hold of, will keep their hold of. "That thou mayest imitate those excellent persons, the patriarchs and prophets (so bishop Patrick paraphrases it), and be preserved in the paths of those righteous men who followed after them." We must not only choose our way in general by the good examples of the saints, but must also take directions from them in the choice of our particular paths; observe the track, and go forth by the footsteps of the flock. Two reasons are here given why we should thus choose:-- (1.) Because men's integrity will be their establishment, v. 21. It will be the establishment, [1.] Of their persons: The upright shall dwell in the land, peaceably and quietly, as long as they live; and their uprightness will contribute to it, as it settles their minds, guides their counsels, gains them the good-will of their neighbours, and entitles them to God's special favour. [2.] Of their families: The perfect, in their posterity, shall remain in it. They shall dwell and remain for ever in the heavenly Canaan, of which the earthly one was but a type. (2.) Because men's iniquity will be their destruction, v. 22. See what becomes of the wicked, who choose the way of the evil man; they shall be cut off, not only from heaven hereafter and all hopes of that, but from the earth now, on which they set their affections, and in which they lay up their treasure. They think to take root in it, but they and their families shall be rooted out of it, in judgment to them, but in mercy to the earth. There is a day coming which shall leave them neither root nor branch, Mal. iv. 1. Let that wisdom then enter into our hearts, and be pleasant to our souls, which will keep us out of a way that will end thus.

Proverbs 22:18

17 Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge. 18 For it is a pleasant thing if thou keep them within thee; they shall withal be fitted in thy lips. 19 That thy trust may be in the LORD, I have made known to thee this day, even to thee. 20 Have not I written to thee excellent things in counsels and knowledge, 21 That I might make thee know the certainty of the words of truth; that thou mightest answer the words of truth to them that send unto thee?

Solomon here changes his style and manner of speaking. Hitherto, for the most part, since the beginning of ch. x., he had laid down doctrinal truths, and but now and then dropped a word of exhortation, leaving us to make the application as we went along; but here, to the end of ch. xxiv., he directs his speech to his son, his pupil, his reader, his hearer, speaking as to a particular person. Hitherto, for the most part, his sense was comprised in one verse, but here usually it is drawn out further. See how Wisdom tries variety of methods with us, lest we should be cloyed with any one. To awaken attention and to assist our application the method of direct address is here adopted. Ministers must not think it enough to preach before their hearers, but must preach to them, nor enough to preach to them all in general, but should address themselves to particular persons, as here: Do thou do so and so. Here is,

I. An earnest exhortation to get wisdom and grace, by attending to the words of the wise men, both written and preached, the words of the prophets and priests, and particularly to that knowledge which Solomon in this book gives men of good and evil, sin and duty, rewards and punishments. To these words, to this knowledge, the ear must be bowed down in humility and serious attention and the heart applied by faith, and love, and close consideration. The ear will not serve without the heart.

II. Arguments to enforce this exhortation. Consider,

1. The worth and weight of the things themselves which Solomon in this book gives us the knowledge of. They are not trivial things, for amusements and diversion, not jocular proverbs, to be repeated in sport and in order to pass away time. No; they are excellent things, which concern the glory of God, the holiness and happiness of our souls, the welfare of mankind and all communities; they are princely things (so the word is), fit for kings to speak and senates to hear; they are things that concern counsels and knowledge, that is, wise counsels, relating to the most important concerns; things which will not only make us knowing ourselves, but enable us to advise others.

2. The clearness of the discovery of these things and the directing of them to us in particular. "They are made known, publicly known, that all may read,--plainly known, that he that runs may read,--made known this day more fully than ever before, in this day of light and knowledge,--made known in this thy day. But it is only a little while that this light is with thee; perhaps the things that are this day made known to thee, if thou improve not the day of thy visitation, may, before to-morrow, be hidden from thy eyes. They are written, for the greater certainty, and that they may be received and the more safely transmitted pure and entire to posterity. But that which the emphasis is here most laid upon is that they are made known to thee, even to thee, and written to thee, as if it were a letter directed to thee by name. It is suited to thee and to thy case; thou mayest in this glass see thy own face; it is intended for thee, to be a rule to thee, and by it thou must be judged." We cannot say of these things, "They are good things, but they are nothing to us;" no, they are of the greatest concern imaginable to us.

3. The agreeableness of these things to us, in respect both of comfort and credit. (1.) If we hide them in our hearts, they will be very pleasing and yield us an abundant satisfaction (v. 18): "It is a pleasant thing, and will be thy constant entertainment, if thou keep them within thee; if thou digest them, and be actuated and governed by them, and delivered into them as into a mould." The form of godliness, when that is rested in, is but a force put upon a man, and he does but do penance in that white clothing; those only that submit to the power of godliness, and make heart-work of it, find the pleasure of it, ch. ii. 10. (2.) If we make use of them in our discourse, they will be very becoming, and gain us a good reputation. They shall be fitted in thy lips. "Speak of these things, and thou speakest like thyself, and as is fit for thee to speak considering thy character; thou wilt also have pleasure in speaking of these things as well as in thinking of them."

4. The advantage designed us by them. The excellent things which God has written to us are not like the commands which the master gives his servant, which are all intended for the benefit of the master, but like those which the master gives his scholar, which are all intended for the benefit of the scholar. These things must be kept by us, for they are written to us, (1.) That we may have a confidence in him and communion with him. That thy trust may be in the Lord, v. 19. We cannot trust in God except in the way of duty; we are therefore taught our duty, that we may have reason to trust in God. Nay, this is itself one great duty we are to learn, and a duty that is the foundation of all practical religion, to live a life of delight in God and dependence on him. (2.) That we may have a satisfaction in our own judgment: "That I might make thee know the certainty of the words of truth; that thou mayest know what is truth, mayest plainly distinguish between it and falsehood, and mayest know upon what grounds thou receivest and believest the truths of God." Note, [1.] It is a desirable thing to know, not only the words of truth, but the certainty of them, that our faith may be intelligent and rational, and may grow up to a full assurance. [2.] The way to know the certainty of the words of truth is to make conscience of our duty; for, if any man do his will, he shall know for certain that the doctrine is of God, John vii. 17. (3.) That we may be useful and serviceable to others for their instruction: "That thou mayest give a good account of the words of truth to those that send to thee to consult thee as an oracle," or (as the margin reads it) "to those that send thee, that employ thee as an agent or ambassador in any business." Knowledge is given us to do good with, that others may light their candle at our lamp, and that we may in our place serve our generation according to the will of God; and those who make conscience of keeping God's commandments will be best able to give a reason of the hope that is in them.
