Here the apostle resumes his argument and exhortation, founding it on his former allusion, You are God’s building, 1 Cor. 3:9; and here, Know you not that you are the temple of God, and the Spirit of God dwelleth in you? If any man defile (corrupt and destroy) the temple of God, him shall God destroy (the same word is in the original in both clauses); for the temple of God is holy, which temple you are. It looks from other parts of the epistle, where the apostle argues to the very same purport (see 1 Cor. 6:13-20), as if the false teachers among the Corinthians were not only loose livers, but taught licentious doctrines, and what was particularly fitted to the taste of this lewd city, on the head of fornication. Such doctrine was not to be reckoned among hay and stubble, which would be consumed while the person who laid them on the foundation escaped the burning; for it tended to corrupt, to pollute, and destroy the church, which was a building erected for God, and consecrated to him, and therefore should be kept pure and holy. Those who spread principles of this sort would provoke God to destroy them. Note, Those who spread loose principles, that have a direct tendency to pollute the church of God, and render it unholy and unclean, are likely to bring destruction on themselves. It may be understood also as an argument against their discord and factious strifes, division being the way to destruction. But what I have been mentioning seems to be the proper meaning of the passage: Know you not that you are the temple of God, and that the Spirit of God dwelleth in you? It may be understood of the church of Corinth collectively, or of every single believer among them; Christian churches are temples of God. He dwells among them by his Holy Spirit. They are built together for a habitation of God through the Spirit, Eph. 2:22. Every Christian is a living temple of the living God. God dwelt in the Jewish temple, took possession of it, and resided in it, by that glorious cloud that was the token of his presence with that people. So Christ by his Spirit dwells in all true believers. The temple was devoted and consecrated to God, and set apart from every common to a holy use, to the immediate service of God. So all Christians are separated from common uses, and set apart for God and his service. They are sacred to him—a very good argument this against all fleshly lusts, and all doctrines that give countenance to them. If we are the temples of God, we must do nothing that shall alienate ourselves from him, or corrupt and pollute ourselves, and thereby unfit ourselves for his use; and we must hearken to no doctrine nor doctor that would seduce us to any such practices. Note, Christians are holy by profession, and should be pure and clean both in heart and conversation. We should heartily abhor, and carefully avoid, what will defile God’s temple, and prostitute what ought to be sacred to him.
