The Word of God is Not Bound
The Apostle Paul’s ministry was initially split. For, after “the fall” of Israel with their murder of Stephen in Acts 7 (cf. Rom. 11:10-12, 15, 25), the Lord saved Paul and said this of Paul’s calling;
“… for he [Paul] is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:” (Acts 9:15 (KJV)
Though Paul is “the Apostle to the Gentiles” (Rom. 11:13) his association was at first with the Jews. As instructed, he went “to the Jew first” in the synagogues of every city he visited, and yet also the Gentiles in forming “the body of Christ” during his Acts period missionary journeys. So, Paul had also turned “far hence” (Acts 22:21) to the Gentiles.
It was after the close of the Acts period (cf. Acts 28:28) that Israel was fully set aside (Acts 28:28). During and then after Paul’s post-Acts imprisonment, his writings and ministry was exclusively to the Gentile church called “the body of Christ” as seen in his last seven epistles of Romans through Philemon. With Israel’s fall, there was then no racial distinction among men – under Paul’s grace gospel Jew and Gentile were equal in God’s eyes.
The attached slide with its text makes it clear how that Paul, even though he was then free in the body he was yet “bound in the spirit” during his mission, having received an “abundance of revelations” (2Cor 12:7) from the Lord. Thus, with Paul’s 2nd imprisonment, then ‘bound in the flesh,’ he was able to say to the Gentile churches “THE WORD OF GOD IS NOT BOUND.” Now Paul could share all that he had received through the multiple revelations given him of the grace of God.
Paul, according to “the revelation of the Mystery,” saw that “the Body of Christ” is a heaven bound, heavenly people, already “blessed with all spiritual blessings in heavenly places” (Eph 1:3).
