Taking its start from our groaning for the hoped-for deliverance, the Apostle begins to speak about hope. He explains its qualities and the firm grounds of its unshakenness.
These grounds are: first, the firstfruits of the Spirit (see Rom 8:23-27). Second, the eternal decree concerning those being saved (see Rom 8:28-30).
Third, the price of the incarnate divine economy (see Rom 8:31-34). All these grounds rest upon unfailing love (see Rom 8:35-39).
The first ground of Christian hope is the firstfruits of the Spirit. The Apostle fixes attention on them in the present text, as that from which hope of complete deliverance is born and by which it is upheld.
The firstfruits of the Spirit are the forgiveness of sins, power to resist sin, peace of conscience, filial boldness toward God, and in many, special gifts of the Holy Spirit.
All this is a good guarantee that the work of deliverance has already begun. It has begun, is being accomplished, and gives a foretaste of what will be at the end.
Yet this foretaste gives birth to groaning, so that what is awaited may more quickly become reality. For what exactly do we groan in expectation? “Waiting for adoption.”
But we have already received the spirit of adoption. What, then, remains to await? The brightness of a state corresponding to sonship.
Not everything in us is yet in order. From without there are great assaults, and the body is corruptible.
Therefore we groan that all this may pass away, that all constraints and dangers may pass, and that the body may rise. Then we shall appear as sons in the full brightness of sonship.
Saint Chrysostom says: “We too groan, as those who have already tasted the future blessings beforehand.
“What has already been given us is enough to awaken even a man of stone, to draw him away from the present, and to give him wings toward the future.
“This is so both because of the greatness of what has been given, and because these exalted and numerous gifts are only the firstfruits.
“If the firstfruits are such that through them we are freed from sins and acquire righteousness and sanctification, and if the Apostles cast out demons by their shadow and raised the dead by their garments, then imagine what all the future blessings will be.
“And if creation groans, though it is deprived of reason and the gift of speech, and has no knowledge of all these things, then much more ought we to groan.
“But so that the heretics might have no occasion to think that the Apostle condemns the present, he goes on to say: we groan not in condemnation of all that is present, but out of desire for something greater.
“He expressed this very thing in the words: ‘waiting for adoption.’ What are you saying, Paul?
“Why do you turn back and forth? At one moment you cry out that we have already become sons. Then you again count this blessing among the objects of hope and write that we must still receive it.
“The Apostle corrects this by adding the words, ‘the redemption of our body,’ that is, perfect glory.
“Now our lot is still hidden in mystery until our last breath. But when we depart from here with a good hope, then the gift will become inalienable, most evident, and greater.
“Then there will be no fear that sin and death may take anything from it. Only then will grace become unchangeable, when the body itself is freed from death and countless sufferings.
“The word ‘redemption’ means not a simple ransom, but one after which we shall no longer return to our former captivity.
“And so that you may not fall into perplexity when you continually hear of glory and have no clear conception of it, the Apostle reveals the future blessings in detail.
“He changes your body, and in accordance with it, all creation. He expressed this more clearly elsewhere, saying, ‘He will transform our lowly body, that it may be conformed to His glorious body’ (Phil 3:21).
“And in another epistle, he says: ‘When this mortal has put on immortality, then shall come to pass the saying that is written: Death is swallowed up in victory’ (cf. 1 Cor 15:54).
“To prove that with the destruction of the body all earthly life also undergoes a change in its state, the Apostle wrote elsewhere: ‘For the form of this world is passing away’ (1 Cor 7:31).”
Ambrosiaster pays special attention to why we groan: “After creation, the Apostle adds that we also groan, that we may be delivered from here, since we have been appointed for the blessed life.
“For this world is a sea for Christians. As the sea, stirred by contrary winds, attacks those who sail and exposes them to danger, so this age troubles the minds of believers by the cunning of hostile movements.
“The enemy does this with such variety that one does not know from what to be delivered first.
“If authority ceases to oppose us, he stirs up private persons. If these too are quiet, he kindles a fire through household members.
“If this also gives him no handhold, he sows discord among relatives by his malice, so that the house, struck from four corners, may crack in some part.
“For this reason Christians must desire with all their soul to escape from here more quickly.
“Let Simeon be their example in this. Knowing with what cunning the opposing warfare is waged here, he prayed to be dismissed in peace (see Lk 2:29).
“We all pray for this same thing when we say, ‘Thy kingdom come’ (cf. Mt 6:10).
“The Apostle, as a divine man, has good thoughts concerning us when he says that we groan for deliverance from here, as Simeon groaned. But I see that we are greatly held by the delights of the world.”
Photius, in Oecumenius, reasons: “‘Waiting for adoption.’ What adoption? Have we not already received it through holy Baptism?
“And did you not yourself say a little earlier that we have received the spirit of adoption? Yes, he says. What adoption, then, must we still await?
“He says: that which is manifest to all, accompanied by the redemption of the body from corruption.
“What then? Will this be something other than what has been said? By no means. It is the same thing, only manifested in perfection, visible and known to all.
“For then, after the resurrection of the body and the reception of incorruption, there will be full enjoyment of the promised blessings, the inheritance of the Kingdom of Heaven, and entrance into all the privileges of sonship.
“And now, in the hope of receiving all this, we have received adoption.”
