All who are led by the Spirit of God are God’s children
Those who live according to the flesh are intent on the things of the flesh, those who live according to the spirit, on those of the spirit. The tendency of the flesh is toward death but that of the spirit toward life and peace. The flesh in its tendency is at enmity with God; it is not subject to God’s law. Indeed, it cannot be; those who are in the flesh cannot please God.
But you are not in the flesh; you are in the spirit, since the Spirit of God dwells in you. If anyone does not have the Spirit of Christ, he does not belong to Christ. If Christ is in you the body is dead because of sin, while the spirit lives because of justice. If the Spirit of him who raised Jesus from the dead dwells in you, then he who raised Christ from the dead will bring your mortal bodies to life also, through his Spirit dwelling in you.
We are debtors, then, my brothers—but not to the flesh, so that we should live according to the flesh. If you live according to the flesh, you will die; but if by the spirit you put to death the evil deeds of the body, you will live.
All who are led by the Spirit of God are sons of God. You did not receive a spirit of slavery leading you back into fear, but a spirit of adoption through which we cry out, “Abba!” (that is, “Father”). The Spirit himself gives witness with our spirit that we are children of God. But if we are children, we are heirs as well: heirs of God, heirs with Christ, if only we suffer with him so as to be glorified with him.
I consider the sufferings of the present to be as nothing compared with the glory to be revealed in us. Indeed, the whole created world eagerly awaits the revelation of the sons of God. Creation was made subject to futility, not of its own accord but by him who once subjected it; yet not without hope, because the world itself will be freed from its slavery to corruption and share in the glorious freedom of the children of God. Yes, we know that all creation groans and is in agony even until now. Not only that, but we ourselves, although we have the Spirit as first fruits, groan inwardly while we await the redemption of our bodies. In hope we were saved. But hope is not hope if its object is seen; how is it possible for one to hope for what he sees? And hoping for what we cannot see means awaiting it with patient endurance.
The Spirit too helps us in our weakness, for we do not know how to pray as we ought; but the Spirit himself makes intercession for us with groanings that cannot be expressed in speech. He who searches hearts knows what the Spirit means, for the Spirit intercedes for the saints as God himself wills.
