Romans 8:17-18

Verse 17. And if children. If adopted into his family.

Then heirs. That is, he will treat us as sons. An heir is one who succeeds to an estate. The meaning here is, that if we sustain the relation of sons to God that we shall be treated as such, and admitted to share his favours. An adopted son comes in for a part of the inheritance, Nu 27.

Heirs of God. This expression means, that we shall be partakers of that inheritance which God confers on his people. That inheritance is his favour here, and eternal life hereafter. This is an honour infinitely higher than to be heir to the most princely earthly inheritance; or than to be the adopted son of the most magnificent earthly monarch.

And joint-heirs with Christ. Christ is by eminence THE Son of God. As such, he is heir to the full honours and glory of heaven. Christians are united to him; they are his friends; and they are thus represented as destined to partake with him of his glory. They are the sons of God in a different sense from what he is; he by his nature and high relation, they by adoption; but still the idea of sonship exists in both; and hence both will partake in the glories of the eternal inheritance. Comp. Php 2: 8, 9, Heb 2: 9,10. The connexion between Christ and Christians is often referred to in the New Testament. The fact that they are united here is often alleged as a reason why they will be in glory. Jn 14:19, "Because I live, ye shall live also." 2Ti 2:11,12, "For if we be dead with him, we shall also live with him; if we suffer, we shall also reign with him." Rev 3:21, "To him that overcometh will I grant to sit with me in my throne," etc. Jn 17:22-24.

If so be. If this condition exist. We shall not be treated as co-heirs with him, unless we here give evidence that we are united to him.

That we suffer with him. Greek, "If we suffer together, that we may also be glorified together." If we suffer in his cause; bear afflictions as he did; are persecuted and tried for the same thing; and thus show that we are united to him. It does not mean that we suffer to the same extent that he did, but we may imitate him in the kind of our sufferings, and in the spirit with which they are borne; and thus show that we are united to him.

That we may be also glorified together. If united in the same kind of sufferings, there is propriety in being united in destiny beyond the scenes of all suffering, the kingdom of blessedness and love.
Verse 18. For I reckon. I think; I judge. This verse commences a new division of the subject, which is continued to Rom 8:25. Its design is to show the power of the gospel in sustaining the soul in trials: a very important and material part of the scheme. This had been partially noticed before, (Rom 5:3-5) but its full power to support the sold in the prospect of a glorious immortality had not been fully discussed. This topic seems here to have been suggested by what is said of adoption. The mind of the apostle instantly adverted to the effects or benefits of that adoption; and one of the most material of those benefits was the sustaining grace which the gospel imparted in the midst of afflictions. It should be borne in mind, that the early Christians were comparatively few and feeble, and exposed to many trials, and that this topic would be often, therefore, introduced into the discussions about theft privileges and condition.

The sufferings. The afflictions; the persecutions, sicknesses, etc. The expression evidently includes not only the peculiar trials of Christians at that time, but all that believers are ever called to endure.

Of this present time. Probably the apostle had particular reference to the various calamities then endured. But the expression is equally applicable to afflictions of all times and in all places.

Are not worthy to be compared. Are nothing in comparison; the one is far more than an equivalent in compensation for the other.

With the glory. The happiness; the honour in heaven.

Which shall be revealed in us. That shall be disclosed to us; or of which we shall be the partakers in heaven. The usual representation of heaven is that of glory, splendour, magnificence, or light. Comp. Rev 21:10,23,24, 22:5.

By this, therefore, Christians may be sustained. Their sufferings may seem great; but they should remember that they are nothing in comparison with future glory. They are nothing in degree. For these are light compared with that "eternal weight of glory" which they shall "work out," 2Cor 4:17. They are nothing in duration. For these sufferings are but for a moment; but the glory shall be eternal. These will soon pass away; but that glory shall never become dim or diminished, it will increase and expand for ever and ever.

In us. Unto us, (ειςημας).
