1 Corinthians 3:19

For the wisdom of this world is foolishness with God. For it is written, He that taketh the wise in their craftiness:

'is foolishness with God' -'For this world's cleverness is stupidity to God.' (Phi) Especially the "wisdom" that the world uses in the attempt to solve it's own problems and to deliver itself. And remember, ultimately, God's perspective is the only one that really counts.

'And how do we know? Because once again, as in 1 Corinthians 1:19, there is sufficient evidence from what "is written"..' (Fee p. 152)

'He that taketh the wise in their craftiness' -'He traps the wise in their own cunning' (NEB); 'God uses man's own brilliance to trap him.' (Tay) (Job 2:13) 'When the world's schemers think themselves cleverest, Providence catches them in their own toils.' (Gr. Ex. N.T. p. 794)

'The very acts which man considers to be the heights of his wisdom are the acts which lead to his own downfall (cf. Romans 1:21)' (Willis p. 120)
