Romans 8:9

“But ye are not in the flesh, but in the Spirit, etc..] That is, ye are not carnal, but spiritual men; or ye are not in a state of unregeneracy, but in a state of grace: the reason proving this is, if so be, or “seeing” that the Spirit of God dwell in you; the inhabitation of the Spirit is a distinguishing character of a regenerate man; which is to be understood not of his omnipresence, nor of a participation of his gifts, whether ordinary or extraordinary: nor does the Spirit of God only dwell in his people by his graces, but in person as in office, and in a way of special favour; as a spirit of illumination, regeneration, sanctification, and faith, as a comforter, a spirit of adoption, an…”

“But ye are not in the flesh, but in the spirit, if so be that the Spirit of God dwell in you--This does not mean, "if the disposition or mind of God dwell in you"; but "if the Holy Ghost dwell in you" (see Co1 6:11, Co1 6:19; Co1 3:16, &c.). (It thus appears that to be "in the spirit" means here to be under the dominion of our own renewed mind; because the indwelling of God's Spirit is given as the evidence that we are "in the spirit"). Now--"But." if any man have not the Spirit of Christ--Again, this does not mean "the disposition or mind of Christ," but the Holy Ghost; here called "the Spirit of Christ," just as He is called "the Spirit of life in Christ Jesus" (see on Rom 8:2). It is as…”

“But ye - You who are Christians. This is the opposite character to what he had been describing, and shows the power of the gospel. Not in the flesh - Not under the full influence of corrupt desires and passions. But in the Spirit - That is, you are spiritually minded; you are under the direction and influence of the Holy Spirit. The Spirit of God - The Holy Spirit. Dwell in you - The Holy Spirit is often represented as dwelling in the hearts of Christians (compare 1 Corinthians 2:16; 1Co 6:19; 2 Corinthians 6:16; Ephesians 2:21-22; Galatians 4:6); and the meaning is not that there is a personal or physical indwelling of the Holy Spirit, but that he influences, directs, and guides Christians,…”

“In the Spirit - Under his government. If any man have not the Spirit of Christ - Dwelling and governing in him. He is none of his - He is not a member of Christ; not a Christian; not in a state of salvation. A plain, express declaration, which admits of no exception. He that hath ears to hear, let him hear! Romans 8:10”

“8:9 You are controlled by the Spirit: In contrast to unbelievers, who continue to live under the domination of Adam’s sinful nature, believers are directed in their lives by the Holy Spirit. The Spirit does not take away human initiative or make it impossible for believers to sin. However, as the most powerful force in believers’ lives, the Spirit makes it possible for them to resist the continuing power of sin.”

“But ye: Rom 8:2; Eze 11:19, Eze 36:26, Eze 36:27; Joh 3:6 if so be: Rom 8:11; Luk 11:13; Co1 3:16, Co1 6:19; Co2 6:16; Gal 4:6; Eph 1:13, Eph 1:17, Eph 1:18, Eph 2:22; Ti2 1:14; Jo1 3:24, Jo1 4:4; Jde 1:19-21 the Spirit: Joh 3:34; Gal 4:6; Phi 1:19; Pe1 1:11 he is: Joh 17:9, Joh 17:10; Co1 3:21-23, Co1 15:23; Co2 10:7; Gal 5:24; Rev 13:8, Rev 20:15 Romans 8:10”
