Circumcision is nothing and uncircumcision is nothing. Keeping God’s commandments is what counts.
19. Circumcision is nothing While this similitude was suited to the subject in hand, it appears to have been designedly made use of with the view of reproving, in passing, the superstition and haughtiness of the Jews. For, as the Jews gloried in circumcision, it was possible that many might feel dissatisfied with the want of it, as if their condition were the worse on that account.
Here the apostle takes occasion to advise them to continue in the state and condition in which Christianity found them, and in which they became converts to it. And here, I. He lays down this rule in general - as God hath distributed to every one. Note, Our states and circumstances in this world are distributions of divine Providence. This fixes the bounds of men's habitations, and orders their steps.
Commenting on 1 Corinthians 7:17-24
Circumcision is nothing,.... In the affair of justification before God, and acceptance with him; it cannot make any man righteous in the sight of God, nor recommend him to the divine favour; it is no evidence of a man's calling, or of his having the truth or grace of God in him; nor is it of any avail in the business of salvation.
