15. He now confirms the certainty of that confidence, in which he has already bidden the faithful to rest secure; and he does this by mentioning the special effect produced by the Spirit; for he has not been given for the purpose of harassing us with trembling or of tormenting us with anxiety; but on the contrary, for this end -- that having calmed every perturbation, and restoring our minds to a tranquil state, he may stir us up to call on God with confidence and freedom. He does not then pursue only the argument which he had before stated, but dwells more on another clause, which he had connected with it, even the paternal mercy of God, by which he forgives his people the infirmities of the flesh and the sins which still remain in them. He teaches us that our confidence in this respect is made certain by the Spirit of adoption, who could not inspire us with confidence in prayer without sealing to us a gratuitous pardon: and that he might make this more evident, he mentions a twofold spirit; he calls one the spirit of bondage, which we receive from the law; and the other, the spirit of adoption, which proceeds from the gospel. The first, he says, was given formerly to produce fear; the other is given now to afford assurance. By such a comparison of contrary things the certainty of our salvation, which he intended to confirm, is, as you see, made more evident. ¹ The same comparison is used by the author of the Epistle to the Hebrews, where he says, that we have not come to Mount Sinai, where all thing were so terrible, that the people, being alarmed as it were by an immediate apprehension of death, implored that the word should be no more spoken to them, and Moses himself confessed that he was terrified;

"but to Sion, the mount of the Lord, and to his city, the heavenly Jerusalem, where Jesus is, the Mediator of the New Testament," etc. (Hebrews 12:22,24.)

By the adverb again, we learn, that the law is here compared with the gospel: for the Son of God by his coming has brought to us this invaluable benefit, -- that we are no longer bound by the servile condition of the law. You are not however to infer from this, either that no one before the coming of Christ was endued with the spirit of adoption, or that all who received the law were servants and not sons: for he compares the ministration of the law with the dispensation of the gospel rather than persons with persons. I indeed allow that the faithful are here reminded how much more bountifully God now deals with them than he did formerly with the fathers under the Old Testament; he yet regards the outward dispensation, in respect of which only we excel them: for though the faith of Abraham, of Moses, and of David, was superior to ours, yet as God kept them apparently under a schoolmaster, they had not advanced into that liberty which has been revealed to us.

But it must at the same time be noticed, that it was designedly, on account of false apostles, that a contrast was made between the literal disciples of the law, and the faithful whom Christ, the heavenly Teacher, not only addresses by words, but also teaches inwardly and effectually by his Spirit.

And though the covenant of grace is included under the law, it is yet far different from it; for in setting up the gospel in opposition to it, he regards nothing but what was peculiar to the law itself, as it commands and forbids, and restrains transgressors by the denunciation of death: and thus he gives the law its own character, in which it differs from the gospel; or this statement may be preferred by some, -- "He sets forth the law only, as that by which God covenants with us on the ground of works." So then persons only must be regarded as to the Jewish people; for when the law was published, and also after it was published, the godly were illuminated by the same Spirit of faith; and thus the hope of eternal life, of which the Spirit is the earnest and seal, was sealed on their hearts. The only difference is, that the Spirit is more largely and abundantly poured forth in the kingdom of Christ. But if you regard only the dispensation of the law, it will then appear, that salvation was first clearly revealed at that time, when Christ was manifested in the flesh. All things under the Old Testament were involved in great obscurity, when compared with the clear light of the gospel.

And then, if the law be viewed in itself, it can do nothing but restrain those, devoted to its miserable bondage, by the horror of death; for it promises no good except under condition, and denounces death on all transgressors. Hence, as there is the spirit of bondage under the law, which oppresses the conscience with fear; so under the gospel there is the spirit of adoption, which exhilarates our souls by bearing a testimony as to our salvation. But observe, that fear is connected with bondage, as it cannot be otherwise, but that the law will harass and torment souls with miserable disquietness, as long as it exercises its dominion. There is then no other remedy for quieting them, except God forgives us our sin and deals kindly with us as a father with his children.

Through whom we cry, etc. He has changed the person, that he might describe the common privilege of all the saints; as though he had said, -- "Ye have the spirit, through whom you and all we, the rest of the faithful, cry," etc. The imitation of their language is very significant; when he introduces the word Father, in the person of the faithful. The repetition of the name is for the sake of amplification; for Paul intimates, that God's mercy was so published through the whole world, that he was invoked, as Augustine observes, indiscriminately in all languages. ² His object then was to express the consent which existed among all nations. It hence follows, that there is now no difference between the Jew and the Greek, as they are united together. Isaiah speaks differently when he declares, that the language of Canaan would be common to all, (Isaiah 19:18;) yet the meaning is the same; for he had no respect to the external idiom, but to the harmony of heart in serving God, and to the same undisguised zeal in professing his true and pure worship. The word cry is set down for the purpose of expressing confidence; as though he said, "We pray not doubtingly, but we confidently raise up a loud voice to heaven."

The faithful also under the law did indeed call God their Father, but not with such full confidence, as the vail kept them at a distance from the sanctuary: but now, since an entrance has been opened to us by the blood of Christ, we may rejoice fully and openly that we are the children of God; hence arises this crying. In short, thus is fulfilled the prophecy of Hosea,

"I will say to them, My people are ye: they in their turn will answer, Thou art our God." (Hosea 2:23.)

For the more evident the promise is, the greater the freedom in prayer.

16. The Spirit himself, etc. He does not simply say, that God's Spirit is a witness to our spirit, but he adopts a compound verb, which might be rendered "contest," (contestatur,) were it not that contestation (contestatio) has a different meaning in Latin. But Paul means, that the Spirit of God gives us such a testimony, that when he is our guide and teacher, our spirit is made assured of the adoption of God: for our mind of its own self, without the preceding testimony of the Spirit, could not convey to us this assurance. There is also here an explanation of the former verse; for when the Spirit testifies to us, that we are the children of God, he at the same time pours into our hearts such confidence, that we venture to call God our Father. And doubtless, since the confidence of the heart alone opens our mouth, except the Spirit testifies to our heart respecting the paternal love of God, our tongues would be dumb, so that they could utter no prayers. For we must ever hold fast this principle, -- that we do not rightly pray to God, unless we are surely persuaded in our hearts, that he is our Father, when we so call him with our lips. To this there is a corresponding part, -- that our faith has no true evidence, except we call upon God. It is not then without reason that Paul, bringing us to this test, shows that it then only appears how truly any one believes, when they who have embraced the promise of grace, exercise themselves in prayers. ³

But there is here a striking refutation of the vain notions of the Sophists respecting moral conjecture, which is nothing else but uncertainty and anxiety of mind; nay, rather vacillation and delusion. ⁴ There is also an answer given here to their objection, for they ask, "How can a man fully know the will of God?" This certainly is not within the reach of man, but it is the testimony of God's Spirit; and this subject he treats more at large in the First Epistle to the Corinthians, from which we may derive a fuller explanation of a passage. Let this truth then stand sure, -- that no one can be called a son of God, who does not know himself to be such; and this is called knowledge by John, in order to set forth its certainty. (1 John 5:19, 20.)

17. And if children, etc. By an argument, taken from what is annexed or what follows, he proves that our salvation consists in having God as our Father. It is for children that inheritance is appointed: since God then has adopted us as his children, he has at the same time ordained an inheritance for us. He then intimates what sort of inheritance it is -- that it is heavenly, and therefore incorruptible and eternal, such as Christ possesses; and his possession of it takes away all uncertainty: and it is a commendation of the exellency of this inheritance, that we shall partake of it in common with the only-begotten Son of God. It is however the design of Paul, as it will presently appear more fully, highly to extol this inheritance promised to us, that we may be contented with it, and manfully despise the allurements of the world, and patiently bear whatever troubles may press on us in this life.

If so be that we suffer together, etc. Various are the interpretations of this passage, but I approve of the following in preference to any other, "We are co-heirs with Christ, provided, in entering on our inheritance, we follow him in the same way in which he has gone before." And he thus made mention of Christ, because he designed to pass over by these steps to an encouraging strain, -- "God's inheritance is ours, because we have by his grace been adopted as his children; and that it may not be doubtful, its possession as been already conferred on Christ, whose partners we are become: but Christ came to it by the cross; then we must come to it in the same manner." ⁵ Nor is that to be dreaded which some fear, that Paul thus ascribes the cause of our eternal glory to our labours; for this mode of speaking is not unusual in Scripture. He denotes the order, which the Lord follows in dispensing salvation to us, rather than the cause; for he has already sufficiently defended the gratuitous mercy of God against the merits of works. When now exhorting us to patience, he does not show whence salvation proceeds, but how God governs his people.

18. I indeed judge, ⁶ etc. Though they take not altogether an unsuitable view who understand this as a kind of modification; yet I prefer to regard it in the light of an encouragement, for the purpose of anticipating an objection, according to this import, -- "It ought not indeed to be grievous to us, if we must pass through various afflictions into celestial glory, since these, when compared with the greatness of that glory, are of the least moment." He has mentioned future for eternal glory, intimating that the afflictions of the world are such as pass away quickly.

It is hence evident how ill understood has this passage been by the Schoolmen; for they have drawn from it their frivolous distinction between congruity and condignity. The Apostle indeed compares not the worthiness of the one with that of the other, but only lightens the heaviness of the cross by a comparison with the greatness of glory, in order to confirm the minds of the faithful in patience.
