And not only they, but ourselves also, who have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, that is, the redemption of our body.
All Commentaries on Romans 8:23 Go To Romans 8
Augustine of Hippo
AD 430
Paul now speaks about those of us who already believe. For although we serve the law of God with our spirit (i.e., our mind), our flesh still serves the law of sin for as long as we suffer mortal pains and anxieties…. Adoption is already guaranteed for those who believe, but it has been accomplished only spiritually, not physically. The body has not yet received its heavenly transformation, although the spirit, which has turned from its errors to God, has already been changed through the reconciliation of faith. Therefore even believers still await the revelation which will come in the resurrection of the body. This is the fourth state, when everything will be in perfect peace at eternal rest, completely free of malignant corruption or nagging torment.
