رومية ٨:١٠

And if Christ be in you--by His indwelling Spirit in virtue of which we have one life with him. the body--"the body indeed." is dead because of--"by reason of" sin; but the spirit is life because--or, "by reason" of righteousness--The word "indeed," which the original requires, is of the nature of a concession--"I grant you that the body is dead . . . and so far redemption is incomplete, but," &c.; that is, "If Christ be in you by His indwelling Spirit, though your 'bodies' have to pass through the stage of 'death' in consequence of the first Adam's 'sin,' your spirit is instinct with new and undying 'life,' brought in by the 'righteousness' of the second Adam" [THOLUCK, MEYER, and ALFORD in part, but only HODGE entirely].

In these verses the apostle represents two more excellent benefits, which belong to true believers. I. Life. The happiness is not barely a negative happiness, not to be condemned; but it is positive, it is an advancement to a life that will be the unspeakable happiness of the man (Rom 8:10, Rom 8:11): If Christ be in you. Observe, If the Spirit be in us, Christ is in us. He dwells in the heart by faith, Eph 3:17. Now we are here told what becomes of the bodies and souls of those in whom Christ is. 1. We cannot say but that the body is dead; it is a frail, mortal, dying body, and it will be dead shortly; it is a house of clay, whose foundation is in the dust. The life purchased and promised does not immortalize the body in its present state. It is dead, that is, it is appointed to die, it is under a sentence of death: as we say one that is condemned is a dead man. In the midst of life we are in death: be our bodies ever so strong, and healthful, and handsome, they are as good as dead (Heb 11:12), and this because of sin. It is sin that kills the body. This effect the first threatening has (Gen 3:19): Dust thou art. Methinks, were there no other argument, love to our bodies should make us hate sin, because it is such an enemy to our bodies. The death even of the bodies of the saints is a remaining token of God's displeasure against sin. 2. But the spirit, the precious soul, that is life; it is now spiritually alive, nay, it is life. Grace in the soul is its new nature; the life of the saint lies in the soul, while the life of the sinner goes no further than the body. When the body dies, and returns to the dust, the spirit if life; not only living and immortal, but swallowed up of life. Death to the saints is but the freeing of the heaven-born spirit from the clog and load…

8:10 the Spirit gives you life: The Spirit opposes sin (which leads to physical death) and brings resurrection from the dead.
