Romans 8:9

But ye are not in the flesh - Ye Christians, who have believed in Christ Jesus as the sin offering which has condemned sin in the flesh; and, having been justified by faith and made partakers of the Holy Spirit, are enabled to walk in newness of life.

If so be that the Spirit of God dwell in you - Or seeing that, ειπερ , the Spirit of God dwelleth in you. The flesh, the sinful principle, dwelt in them before; and its motions were the proofs of its indwelling; but now the Spirit dwells in them; and its testimony in their conscience, and its powerful operations in their hearts, are the proofs of its indwelling. God made man in union with himself, and his heart was his temple. Sin being committed, the temple was defiled, and God abandoned it. Jesus Christ is come by his sacrifice and Spirit to cleanse the temple, and make man again a habitation of God through the Spirit. And when this almighty Spirit again makes the heart his residence, then the soul is delivered from the moral effects of the fall. And that this is absolutely necessary to our present peace and final salvation is proved from this: that if any man have not the Spirit of Christ - the mind that was in him, produced there by the power of the Holy Ghost - he is none of his; he does not belong to the kingdom, flock, or family of God. This is an awful conclusion! Reader, lay it to heart.
