Matthew Poole and continuators on Romans 8:9

9 But ye are not in the flesh, but in the Spirit , if so be that the Spirit of God dwell in you . Now if any man have not the Spirit of Christ, he is none of his .

Here he applies what he had laid down more generally to the believing Romans in particular.

i. e. Not after the Flesh, but after the Spirit (as in v. 5. or not carnally, but Spiritually minded.

The Conjunction here is causal not conditional; it may be rendred, seeing that, or forasmuch as. vid. v. 17. & 31. 2 Thes. 1.6.

The Spirit of God dwells in the regenerate, not only by the immensity of his presence, so he is every where and in all things: but by the presence and efficacy of his grace; the indwelling of the Spirit in Believers, denotes two things. 1. His ruling in them; where a man dwells as Lord, there he doth command and bear rule. 2. His abiding in them, and that for ever. Iohn 14.16.

If he hath not the same Spirit which in the forgoing verse is called, the Spirit of God; it is called, the Spirit of Christ; because it proceeds from him, and is procured by him. Iohn 14.26. and 16.7. Gal. 4.6. When he saith such a one is none of Christs; he means, that he doth not peculiarly belong to Christ, he hath no special interest in him, is no true Member of him. As a Merchant sets his Seal upon his Goods, so doth Christ his Spirit upon his followers, Eph. 1.13.
