No one should deceive himself. If anyone among you thinks he is wise in this age, he must become foolish so that he can become wise.For the wisdom of this world is foolishness with God, since it is written: He catches the wise in their craftiness;and again, The Lord knows that the reasonings of the wise are meaningless.
So that you will not be conceited, brothers, I do not want you to be unaware of this mystery: A partial hardening has come to Israel until the full number of the Gentiles has come in.
