Let no man deceive himself. If any man among you seems to be wise in this world, let him become a fool, that he may be wise.
All Commentaries on 1 Corinthians 3:18 Go To 1 Corinthians 3
John Chrysostom
AD 407
Paul asks us to become dead to the world, and this deadness is of benefit to us, because it is the beginning of new life. So also he bids us become foolish toward the world, thereby introducing us to true wisdom. You become a fool to this world when you despise earthly wisdom and are persuaded that it contributes nothing to your understanding of the faith. For Christians, everything is just the opposite of what it seems.
