1 Corinthians 3:18

18 Let no one deceive himself; if any one doth seem to be wise among you in this age -- let him become a fool, that he may become wise,

1 Corinthians 3:18 In-Context

16 have ye not known that ye are a sanctuary of God, and the Spirit of God doth dwell in you?
17 if any one the sanctuary of God doth waste, him shall God waste; for the sanctuary of God is holy, the which ye are.
18 Let no one deceive himself; if any one doth seem to be wise among you in this age -- let him become a fool, that he may become wise,
19 for the wisdom of this world is foolishness with God, for it hath been written, `Who is taking the wise in their craftiness;'
20 and again, `The Lord doth know the reasonings of the wise, that they are vain.'
