18 Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.   19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.   20 And again, The Lord knoweth the thoughts of the wise, that they are vain.

      Here he prescribes humility, and a modest opinion of themselves, for the remedy of the irregularities in the church of Corinth, the divisions and contests among them: "Let no man deceive himself, v. 18. Do not be led away from the truth and simplicity of the gospel by pretenders to science and eloquence, by a show of deep learning, or a flourish of words, by rabbis, orators, or philosophers." Note, We are in great danger of deceiving ourselves when we have too high an opinion of human wisdom and arts; plain and pure Christianity will be likely to be despised by those who can suit their doctrines to the corrupt taste of their hearers, and set them off with fine language, or support them with a show of deep and strong reasoning. But he who seems to be wise must become a fool that he may be wise. He must be sensible of his own ignorance, and lament it; he must distrust his own understanding, and not lean on it. To have a high opinion of our wisdom is but to flatter ourselves, and self-flattery is the very next step to self-deceit. The way to true wisdom is to sink our opinion of our own to a due level, and be willing to be taught of God. He must become a fool who would be truly and thoroughly wise. The person who resigns his own understanding, that he may follow the instruction of God, is in the way to true and everlasting wisdom. The meek will he guide in judgment, the meek will he teach his way, Ps. xxv. 9. He that has a low opinion of his own knowledge and powers will submit to better information; such a person may be informed and improved by revelation: but the proud man, conceited of his own wisdom and understanding, will undertake to correct even divine wisdom itself, and prefer his own shallow reasonings to the revelations of infallible truth and wisdom. Note, We must abase ourselves before God if we would be either truly wise or good: For the wisdom of this world is foolishness with God, v. 19. The wisdom which worldly men esteem (policy, philosophy, oratory) is foolishness with God. It is so in a way of comparison with his wisdom. He chargeth his angels with folly (Job iv. 18), and much more the wisest among the children of men. His understanding is infinite, Ps. cxlvii. 5. There can be no more comparison between his wisdom and ours than between his power and being and ours. There is no common measure by which to compare finite and infinite. And much more is the wisdom of man foolishness with God when set in competition with his. How justly does he despise, how easily can he baffle and confound it! He taketh the wise in their own craftiness (Job v. 13), he catches them in their own nets, and entangles them in their own snares: he turns their most studies, plausible, and promising schemes against themselves, and ruins them by their own contrivance. Nay, He knows the thoughts of the wise, that they are vain (v. 20), that they are vanity, Ps. xciv. 11. Note, God has a perfect knowledge of the thoughts of men, the deepest thoughts of the wisest men, their most secret counsels and purposes: nothing is hidden from him, but all things are naked and bare before him, Heb. iv. 13. And he knows them to be vanity. The thoughts of the wisest men in the world have a great mixture of vanity, of weakness and folly, in them; and before God their wisest and best thoughts are very vanity, compared, I mean, with his thoughts of things. And should not all this teach us modesty, diffidence in ourselves, and a deference to the wisdom of God, make us thankful for his revelations, and willing to be taught of God, and not be led away by specious pretences to human wisdom and skill, from the simplicity of Christ, or a regard to his heavenly doctrine? Note, He who would be wise indeed must learn of God, and not set his own wisdom up in competition with God's.

      21 Therefore let no man glory in men. For all things are yours;   22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;   23 And ye are Christ's; and Christ is God's.

      Here the apostle founds an exhortation against over-valuing their teachers on what he had just said, and on the consideration that they had an equal interest in all their ministers: Therefore let no man glory in men (v. 21)-- forget that their ministers are men, or pay that deference to them that is due only to God, set them at the head of parties, have them in immoderate esteem and admiration, and servilely and implicitly follow their directions and submit to their dictates, and especially in contradiction to God and the truths taught by his Holy Spirit. Mankind are very apt to make the mercies of God cross their intentions. The ministry is a very useful and very gracious institution, and faithful ministers are a great blessing to any people; yet the folly and weakness of people may do much mischief by what is in itself a blessing. They may fall into factions, side with particular ministers, and set them at their head, glory in their leaders, and be carried by them they know not whither. The only way to avoid this mischief is to have a modest opinion of ourselves, a due sense of the common weakness of human understanding, and an entire deference to the wisdom of God speaking in his word. Ministers are not to be set up in competition with one another. All faithful ministers are serving one Lord and pursuing one purpose. They were appointed of Christ, for the common benefit of the church: "Paul, and Apollos, and Cephas, are all yours. One is not to be set up against another, but all are to be valued and used for your own spiritual benefit." Upon this occasion also he gives in an inventory of the church's possessions, the spiritual riches of a true believer: "All is yours--ministers of all ranks, ordinary and extraordinary. Nay the world itself is yours." Not that saints are proprietors of the world, but it stands for their sake, they have as much of it as Infinite Wisdom sees to be fit for them, and they have all they have with the divine blessing. "Life is yours, that you may have season and opportunity to prepare for the life of heaven; and death is yours, that you may go to the possession of it. It is the kind messenger that will fetch you to your Father's house. Things present are yours, for your support on the road; things to come are yours, to enrich and regale you for ever at your journey's end." Note, If we belong to Christ, and are true to him, all good belongs to us, and is sure to us. All is ours, time and eternity, earth and heaven, life and death. We shall want no good thing, Ps. lxxxiv. 11. But it must be remembered, at the same time, that we are Christ's, the subjects of his kingdom, his property. He is Lord over us, and we must own his dominion, and cheerfully submit to his command and yield themselves to his pleasure, if we would have all things minister to our advantage. All things are ours, upon no other ground than our being Christ's. Out of him we are without just title or claim to any thing that is good. Note, Those that would be safe for time, and happy to eternity, must be Christ's. And Christ is God's. He is the Christ of God, anointed of God, and commissioned by him, to bear the office of a Mediator, and to act therein for the purposes of his glory. Note, All things are the believer's, that Christ might have honour in his great undertaking, and God in all might have the glory. God in Christ reconciling a sinful world to himself, and shedding abroad the riches of his grace on a reconciled world, is the sum and substance of the gospel.
