Romans 8:10
And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
And if Christ be in you,.... Not as he is in the whole world, and in all his creatures, or circumscriptively, and to the exclusion of himself elsewhere; for his person is above in heaven, his blood is within the vail, his righteousness is upon his people, and his Spirit and grace are in them; and so he comes to be in them, he is formed in their hearts by the Spirit of God in regeneration, when the Father reveals him not only to them, but in them; and he himself enters and takes possession of them as his own, manifests himself to them, communicates his grace, and grants them communion with him. This being their case,
the body is dead because of sin: by which is meant, not the body of sin, though this is called a body, and a body of death, yet is not dead, much less is it so by reason of sin; but this fleshly body, because liable to afflictions, which are called deaths, has the seeds of mortality in it, and shall in a little time die, notwithstanding the gift of it to Christ, though it is redeemed by his blood, and united to him; the reason of it is not merely the decree of God, nor does it arise from the original constitution of the body, but sin is the true reason of it, sin original and actual, indwelling sin, but not by way of punishment for it, for Christ has bore that, death is one of the saints' privileges, it is for their good, and therefore desired by them; but that they might be rid of it, and free from all those troubles which are the consequences of it:
but the Spirit is life, because of righteousness; not the Spirit of God, who lives in himself, is the author of life to others, of natural and spiritual life, continues as a principle of life in the saints, is the pledge of everlasting life, and is so to them because of the righteousness of Christ nor grace, or the new creature, which is sometimes called Spirit, and may be said to be life, it lives unto righteousness, and is owing to and supported by the righteousness of the Son of God; but the soul of man is here meant, in opposition to the body, which is of a spiritual nature, immaterial and immortal; and this may be said in believers to be life or live, for it not only lives naturally, but spiritually; it lives a life of holiness from Christ, a life of faith upon him, and a life of justification by him, and will live eternally; first in a separate state from the body after death, till the resurrection morn, it does not die with the body, nor sleep with it in the grave, nor is it in any "limbus" or state of purgatory, but in paradise, in heaven, in the arms and presence of Christ, where it is not inactive, but employed in the best of service: and after the resurrection it will live with the body in glory for evermore; and this is owing to righteousness, not to the righteousness of man, but the imputed righteousness of Christ; for as it was sin, and loss of righteousness thereby which brought death on man, the righteousness of Christ is that on which believers live now, and is their right and title to eternal life hereafter.
