No Obligation - Romans 8:5-17 (2)
Introduction
Flesh and Spirit (vs. 5–8)
“You have the Spirit” (vs. 9–11)
Paul is teaching that the believer, although still bound to an earthly, mortal body, has residing within him or her the Spirit, the power of new spiritual life, which conveys both that “life,” in the sense of deliverance from condemnation enjoyed now and the future resurrection life that will bring transformation to the body itself. All this takes place “because of righteousness,” this “righteousness” being that “imputed righteousness” which leads to life (see 5:21).
“The Spirit has you!” (vs. 12–17)
In the OT, the “inheritance” is particularly the land, promised to Abraham and his “seed,” a promise that is renewed after the disaster of the Exile. In later Judaism, however, the “inheritance” did not always maintain a distinctive spatial focus and came to be used to describe eschatological life.45 Paul follows in this line by awarding the “inheritance” promised to Abraham to all those who have faith (see Rom. 4:13–15). As he puts it in Galatians, it is Christ who is “the seed of Abraham” and heir to all that has been promised to Abraham; thus, it is those who are “in Christ” who also become the seed of Abraham and heirs of the promise (3:16–18, 29). All this informs Paul’s description of believers in this verse as both “children” and “heirs.” Christians are God’s people of the new age, “children of God,” and, as such, also the recipients of what God has promised to his people.
Christians are, then, “heirs of God”—meaning probably not that Christians inherit God himself, but that they inherit “what God has promised.”48 In immediately adding “fellow heirs with Christ,” Paul is not correcting the first description but filling it out by reminding us that Christians inherit the blessings of God’s kingdom only through, and in, Christ. We, “the sons of God,” are such by virtue of our belonging to the Son of God; and we are heirs of God only by virtue of our union with the one who is the heir of all God’s promises (see Mark 12:1–12; Gal. 3:18–19; Heb.1:2).
