The gospel that Christians preach, "the gospel of the grace of God" and "the gospel of the glory of God", is based on the death and resurrection of Christ, His exaltation at God's right hand, and God’s heart of love flowing out to sinners in need of salvation. Believing this gospel brings you into relationship with God as Father. It rises far higher than the other gospels because it presents the Person of Christ, as a glorified man in heaven, as the object for faith.
The gospel is called "the gospel of the glory" because it takes in not only the sacrificial death of Christ, but also His being raised and seated at the Father's right hand in heaven! The gospel itself is not glorious, but the Person presented in the gospel is glorious. The full Christian gospel not only presents a humbled Man on the earth, but a glorified Man in heaven! Elsewhere we read of "the gospel of the grace of God" (Acts 20:24). These are the two aspects of “the gospel of God” which Paul preached. The gospel of the grace presents God coming down to meet man’s need, and the gospel of the glory presents Christ being raised from the dead and exalted at God's right hand. All of the apostles preached the gospel of the grace of God, but the gospel of the glory was entrusted especially to Paul (1 Tim. 1:11), and most likely it is the gospel in this aspect that he elsewhere refers to as "my gospel" (Rom. 2:16; 16:25; 2 Tim. 2:8; 2 Cor. 4:3).
