The Gospel
The Gospel is the good news of Jesus Christ, which Paul is set apart to proclaim. It is the power of God for salvation to everyone who believes.
The Gospel reveals God's righteousness and is central to the Christian faith, emphasizing salvation through faith in Jesus Christ.
In the Greco-Roman world, 'gospel' was often used to announce good news, such as the birth of an emperor. Paul redefines it as the message of Christ's redemptive work.
