“And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.”
King James Version (KJV)
8:23 And even we, who have the first - fruits of the Spirit - That is, the Spirit, who is the first - fruits of our inheritance. The adoption - Persons who had been privately adopted among the Romans were often brought forth into the forum, and there publicly owned as their sons by those who adopted them. So at the general resurrection, when the body itself is redeemed from death, the sons of God shall be publicly owned by him in the great assembly of men and angels. The redemption of our body - From corruption to glory and immortality.
Ro 8:23 Not only [they], but ourselves also. Not only does the world groan, but Christians, though they have the firstfruits of the Spirit, a pledge of a rich and full harvest, groan. There is an eager longing for the fuller enjoyment promised. Waiting for the adoption. We are already adopted children, but rather in expectation that in realization. We have not received the inheritance, the full "revealing of the sons of God" (Ro 8:19, Revised Version). The redemption of our body. When the full adoption comes, we will not have these poor, frail, dying bodies, subject to weakness, sinfulness and decay, but spiritual bodies. "For in this we do groan, earnestly desiring to be clothed upon with our house which is from heaven" (2Co 5:2).
