1 Corinthians 3:18-23
(18) 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.
(19) For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
(20) And again, The Lord knoweth the thoughts of the wise, that they are vain.
(21) Therefore let no man glory in men. For all things are yours;
(22) Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;
(23) And ye are Christ's; and Christ is God's.
3:18-23. Since this was so, Paul gave a pointed warning to ministers (vv. 18-20) and to the congregation in Corinth (vv. 21-23). Ministers could avoid self-deception by evaluating their ministries and realizing that the wisdom of this world reflects the mind of Satan (Eph. 2:2) and is foolishness in God’s sight (1 Cor. 3:19). Paul supported this fact by quoting from Job 5:13 and Psalm 94:11. The members needed to see that the practice of boasting (1 Cor. 3:21) about ministers was similarly a self-centered spirit. Instead, they should boast in God (cf. 1:31) to whom they belonged (3:23; cf. 1:2, 15:28) and who was the source of their every blessing (cf. 1:30).
