Romans 16:25

The apostle was confident that God could do for his readers what they needed (cf. Romans 1:11; Ephesians 3:20). The gospel is God’s chief tool to that end. "My gospel" identifies the one that Paul had preached widely and had expounded in this epistle. The "preaching of Jesus Christ" is another name for the gospel that stresses its subject, Jesus Christ. Proclamation follows revelation. The gospel had been hidden in eternity past until God revealed it first in the Old Testament and then fully in the New (cf. Romans 11:25; Galatians 1:12; Galatians 1:15-16; Ephesians 3:9; Colossians 1:26; Colossians 4:3).
