1 Corinthians 8:2

"For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known."

"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."

"Seest thou a man wise in his own conceit? there is more hope of a fool than of him."

"For if a man think himself to be something, when he is nothing, he deceiveth himself."

"For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in."
