The gospel is the good news of the kingdom. But what is this good news that Jesus Christ preached?
Apostle Paul explains what exactly the gospel—the good news—is in his multiple letters to the churches recorded in the New Testament.
Here, Apostle Paul shares with the Colossian church that he is a servant or a minister of the gospel. But when writing to the Church of God in Corinth, he explains that he is a minister of the New Covenant.
Paul described himself as a servant and minister of the gospel as well as a minister of the New Covenant. Through this, we can conclude that the gospel is the New Covenant.
Jesus Christ gave His body and blood through the
New Covenant Passover (
Lk 22:19-20). Through it, we become one body in Jesus (
1Co 10:16-17), receive the promise of eternal life (
Jn 6:53), and become heirs of God (
Ro 8:16-17). And this is the good news—the gospel—of the kingdom that Jesus Christ proclaimed.
