18 ^eLet no one deceive himself. ^fIf anyone among you thinks that he is wise in this age, let him become a fool that he may become wise. 19 For ^gthe wisdom of this world is folly with God. For it is written, ^h“He catches the wise in their craftiness,” 20 and again, ⁱ“The Lord knows the thoughts of the wise, that they are futile.”
