Romans 4:22-24

Verse 22

And therefore it was imputed to him for righteousness - The verse is thus paraphrased by Dr. Taylor: "For which reason God was graciously pleased to place his faith to his account; and to allow his fiducial reliance upon the Divine goodness, power, and faithfulness, for a title to the Divine blessing, which, otherwise, having been an idolater, he had no right to."

Abraham's strong faith in the promise of the coming Savior, for this was essential to his faith, was reckoned to him for justification: for it is not said that any righteousness, either his own, or that of another, was imputed or reckoned to him for justification; but it, i.e. his faith in God. His faith was fully persuaded of the most merciful intentions of God's goodness; and this, which, in effect, laid hold on Jesus Christ, the future Savior, was the means of his justification; being reckoned unto him in the place of personal righteousness, because it laid hold on the merit of Him who died to make an atonement for our offenses, and rose again for our justification.
Verse 23

Now it was not written for his sake alone - The fact of Abraham's believing and receiving salvation through that faith is not recorded as a mere circumstance in the patriarch's life, intended to do him honor: see Rom 4:24.
Verse 24

But for us also - The mention of this circumstance has a much more extensive design than merely to honor Abraham. It is recorded as the model, according to which God will save both Jews and Gentiles: indeed there can be no other way of salvation; as all have sinned, all must either be saved by faith through Christ Jesus, or finally perish. If God, therefore, will our salvation, it must be by faith; and faith contemplates his promise, and his promise comprehends the Son of his love.
