The mystery of the gospel (Rom. 16:25, 26; Eph. 6:19; cf. Lk. 24:44-48; Jn. 3:13-16;
Acts 2:22-36; 5:29-32; 10:36-43; 13:26-39; Rom. 1:1-5, 16, 17; 15:15, 16; 1 Cor. 1:23,
24; 2:1-7; 15:1-11 vv. 3, 4) where the same gospel of Jesus Christ, the Son of God or the
word of Truth about Christ, and Him crucified, that is, His death, burial and resurrection
remains the core Christological message (1 Cor. 1:23, 24; 2:1-5; 15:3, 4); wherein lies the
power of God unto salvation to all that believe (Rom. 1:16, 17; Eph. 1:13).
