{13} But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that {o} dwelleth in you.

(13) A confirmation of the former sentence. You have the very same Spirit which Christ has: therefore at length he will do the same in you, that he did in Christ, that is, when all infirmities being utterly laid aside, and death overcome, he will clothe you with heavenly glory.

(o) By the strength and power of him, who showed the same might first in our head, and daily works in his members.

People's New Testament

8:11 But if the Spirit of him who raised up Jesus from the dead. The Holy Spirit. That Spirit in us is a pledge (see Eph 1:13,14) that God will raise us, even as Christ was raised from the tomb.

Shall also quicken your mortal bodies. Though the body be doomed to death because of sin, it shall be given life for those who have God's Spirit dwelling in them. Even our mortal bodies shall be raised, not in corruption, but in incorruption (1Co 15:42-44).

his Spirit that dwelleth in you-"Your bodies indeed are not exempt from the death which sin brought in; but your spirits even now have in them an undying life, and if the Spirit of Him that raised up Jesus from the dead dwell in you, even these bodies of yours, though they yield to the last enemy and the dust of them return to the dust as it was, shall yet experience the same resurrection as that of their living Head, in virtue of the indwelling of same Spirit in you that quickened Him."

Matthew Henry's Concise Commentary

8:10-17 If the Spirit be in us, Christ is in us. He dwells in the heart by faith. Grace in the soul is its new nature; the soul is alive to God, and has begun its holy happiness which shall endure for ever. The righteousness of Christ imputed, secures the soul, the better part, from death. From hence we see how much it is our duty to walk, not after the flesh, but after the Spirit. If any habitually live according to corrupt lustings, they will certainly perish in their sins, whatever they profess. And what can a worldly life present, worthy for a moment to be put against this noble prize of our high calling? Let us then, by the Spirit, endeavour more and more to mortify the flesh. Regeneration by the Holy Spirit brings a new and Divine life to the soul, though in a feeble state. And the sons of God have the Spirit to work in them the disposition of children; they have not the spirit of bondage, which the Old Testament church was under, through the darkness of that dispensation. The Spirit of adoption was not then plentifully poured out. Also it refers to that spirit of bondage, under which many saints were at their conversion. Many speak peace to themselves, to whom God does not speak peace. But those who are sanctified, have God's Spirit witnessing with their spirits, in and by his speaking peace to the soul. Though we may now seem to be losers for Christ, we shall not, we cannot, be losers by him in the end.
