3:18 {10} 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.
(10) He concludes by the opposite, that they profess pure wisdom in the Church of God, who refuse and cast away all those vanities of men. Further, if they are mocked by the world, it is sufficient for them that they are wise according to the wisdom of God, and as he will have them to be wise.
3:18 Let no man deceive himself. A caution against the philosophical tendencies of the Apolloite party.
If any man among you seemeth to be wise in this world. If he is wise in his own estimation and that of the world calls foolishness (1Co 1:18,23 2:14) in order that he may became wise unto salvation (2Ti 3:15).
3:18 Let him become a fool in this world - Such as the world accounts so. That he may become wise - In God's account.
3:18-23 To have a high opinion of our own wisdom, is but to flatter ourselves; and self-flattery is the next step to self-deceit. The wisdom that wordly men esteem, is foolishness with God. How justly does he despise, and how easily can he baffle and confound it! The thoughts of the wisest men in the world, have vanity, weakness, and folly in them. All this should teach us to be humble, and make us willing to be taught of God, so as not to be led away, by pretences to human wisdom and skill, from the simple truths revealed by Christ. Mankind are very apt to oppose the design of the mercies of God. Observe the spiritual riches of a true believer; All are yours, even ministers and ordinances. Nay, the world itself is yours. Saints have as much of it as Infinite Wisdom sees fit for them, and they have it with the Divine blessing. Life is yours, that you may have a season and opportunity to prepare for the life of heaven; and death is yours, that you may go to the possession of it. It is the kind messenger to take you from sin and sorrow, and to guide you to your Father's house. Things present are yours, for your support on the road; things to come are yours, to delight you for ever at your journey's end. If we belong to Christ, and are true to him, all good belongs to us, and is sure to us. Believers are the subjects of his kingdom. He is Lord over us, we must own his dominion, and cheerfully submit to his command. God in Christ, reconciling a sinful world to himself, and pouring the riches of his grace on a reconciled world, is the sum and substance of the gospel.
