1. Korinther 3:18

seemeth--that is, is, and is regarded by himself and others. wise in this world--wise in mere worldly wisdom (Co1 1:20). let him become a fool--by receiving the Gospel in its unworldly simplicity, and so becoming a fool in the world's sight [ALFORD]. Let him no longer think himself wise, but seek the true wisdom from God, bringing his understanding into captivity to the obedience of faith [ESTIUS].

Here he prescribes humility, and a modest opinion of themselves, for the remedy of the irregularities in the church of Corinth, the divisions and contests among them: "Let no man deceive himself, Co1 3:18. Do not be led away from the truth and simplicity of the gospel by pretenders to science and eloquence, by a show of deep learning, or a flourish of words, by rabbis, orators, or philosophers." Note, We are in great danger of deceiving ourselves when we have too high an opinion of human wisdom and arts; plain and pure Christianity will be likely to be despised by those who can suit their doctrines to the corrupt taste of their hearers, and set them off with fine language, or support them with a show of deep and strong reasoning.

To have a high opinion of our wisdom is but to flatter ourselves, and self-flattery is the very next step to self-deceit. The way to true wisdom is to sink our opinion of our own to a due level, and be willing to be taught of God. He must become a fool who would be truly and thoroughly wise. The person who resigns his own understanding, that he may follow the instruction of God, is in the way to true and everlasting wisdom. The meek will he guide in judgment, the meek will he teach his way, Psa 25:9. He that has a low opinion of his own knowledge and powers will submit to better information; such a person may be informed and improved by revelation: but the proud man, conceited of his own wisdom and understanding, will undertake to correct even divine wisdom itself, and prefer his own shallow reasonings to the revelations of infallible truth and wisdom.

3:18-20 Here Paul returns to the contrast between human wisdom and divine wisdom (see 1:18-25). Using Old Testament quotations, Paul encourages the Corinthians to be willing to appear foolish in the eyes of the world so that they may be truly wise in God’s eyes.
