Romans 16:25-27 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith: To God only wise, be glory through Jesus Christ for ever. Amen. Written to the Romans from Corinthus, and sent by Phebe servant of the church at Cenchrea.
‘Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began.’ This is certainly a second postscript. Some think that Paul added it when he got to Rome and after he had written Ephesians concerning the mystery that had been kept secret from ages past (Eph. 3:1-21). It is in all the MSS but two or three. Some have it after Romans 14:23 and others have it here. Some have it in both places, but there is no question of its genuineness and authenticity.
‘Mystery’ [Greek: musterion] something previously hidden, but now fully revealed. In the New Testament it always means any doctrine that has not, in former times, been made fully known to people. Eighteen mysteries are mentioned in Scripture: The kingdom of heaven and the kingdom of God (Matt. 13:11; Mark 4:11; Luke 8:10); Israel’s blindness (Rom. 11:25); salvation in Christ (Rom. 16:25); the wisdom of God (1Cor. 2:7); the doctrines of God (1Cor. 4:1; Col. 2:2; 1Tim. 3:16); the gospel (Eph. 6:19); the gift of knowledge (1Cor. 13:2); speaking in tongues (1Cor. 14:2); the rapture (1Cor. 15:23, 51-58; John 14:1-3; 1Thess. 4:13-16); God’s will (Eph. 1:9); the body of Christ (Eph. 3:1-9; 5:32); Christ in people (Col. 1:26-27); the doctrines of Christ (Col. 4:3); the spirit of lawlessness (2Thess. 2:7); the faith of the gospel (1Tim. 3:9); the seven candlesticks (Rev. 1:20); God’s delay in casting out of satan (Rev. 10:7; 12:7-17); mystery Babylon (Rev. 17:5, 7).
‘Scriptures of the prophets’ the writings of the prophets – the Old Testament – are part of the Scriptures.
‘Made known to all nations for the obedience of faith.’ The obedience to the faith among all nations are made known through the: the Gospel, the preaching of Jesus Christ and the revelation of the mystery (16:25); scriptures of the prophets and the commandment of God (16:26). The gospel preaching and revelation by the Scriptures must be known and believed in order for the soul to be saved (Mark 16:15-16; John 3:16-20; Rom. 1:16; 10:9-10; Eph. 2:8-9; 1Jn. 1:9; Heb. 11:6).
