In "The Sons of God, Part One," Pastor Robert McNutt of New Covenant Church opens Romans 8:12-17, insisting that the little word "for" in verse 14 ties this new section to the chapter's governing theme: the absolute certainty of the believer's final, complete salvation. Tracing the argument from Romans 5 through 8, he shows that Romans 8 is fundamentally about assurance rather than sanctification, and that Paul frames that assurance in terms of divine sonship. Only those led by the Spirit of God are sons of God, which refutes any notion of the universal fatherhood of God; McNutt marshals John 8:44, John 1:12, John 17, and John 3:16-36 to prove that men are by nature children of wrath and children of the devil until they receive Christ. Rejecting the idea of two tiers of Christians, he argues from Galatians 4 that "sons" and "children" are interchangeable, differing only in a believer's appreciation of his position, not in his relationship. He then centers the doctrine of adoption: an irreversible legal act by which the immutable God takes sinners into His family, so that the forgiven and justified sinner is also adopted, born again, and united to Christ as a fellow heir. Illustrating with the picture of a judge who steps down from the bench to bring the pardoned home, with his own Aunt Mildred, and with the prodigal son of Luke 15, McNutt presses hearers to grasp that assurance and glorification flow from knowing whose they are, and closes by calling the lost to repent and receive Christ and become children of God.
