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.
Seemeth - i:e., is, and is regarded by himself and others.
Wise in this world - wise in mere worldly wisdom (1 Corinthians 1:20).
Let him become a fool - by receiving the Gospel in its unworldly simplicity, and so abjuring worldly wisdom, that law may seek the true wisdom from God, the obedience of faith (Galatians 6:7).
