16 Do you not know that you are a temple of God and that the Spirit of God dwells in you? 17 If any man destroys the temple of God , God will destroy him, for the temple of God is holy , and that is what you are.
18 Let no man deceive himself . If any man among you thinks that he is wise in this age , he must become foolish , so that he may become wise . 19 For the wisdom of this world is foolishness before God . For it is written , "He is THE ONE WHO CATCHES THE WISE IN THEIR CRAFTINESS "; 20 and again , " THE Lord KNOWS THE REASONINGS of the wise , THAT THEY ARE USELESS ."
21 So then let no one boast in men . For all things belong to you, 22 whether Paul or Apollos or Cephas or the world or life or death or things present or things to come ; all things belong to you, 23 and you belong to Christ ; and Christ belongs to God .

Commentary on 1 Corinthians 3:16-17
(Read 1 Corinthians 3:16-17)
From other parts of the epistle, it appears that the false teachers among the Corinthians taught unholy doctrines. Such teaching tended to corrupt, to pollute, and destroy the building, which should be kept pure and holy for God. Those who spread loose principles, which render the church of God unholy, bring destruction upon themselves. Christ by his Spirit dwells in all true believers. Christians are holy by profession, and should be pure and clean, both in heart and conversation. He is deceived who deems himself the temple of the Holy Ghost, yet is unconcerned about personal holiness, or the peace and purity of the church.
Commentary on 1 Corinthians 3:18-23
(Read 1 Corinthians 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.
