Glory is an important concept in Paul’s thinking. Indeed, Richard Gaffin states that the whole of Paul's gospel, centered in Christ’s death and resurrection (Romans 1:3–4; 1 Corinthians 15:3–4), may be viewed as a message of restored and consummated glory.
1 The idea of God’s glory has its roots in the Old Testament, where God’s glory is his visible and active presence in creation; God’s glory is closely related to his grandeur and power as Creator and Redeemer. Because of sin, mankind refuses to honour God, and exchanges his glory for idols (Romans 1:20–23). As a result, the entire human race is cut off from the glory of God (Romans 3:23). The marvel of the gospel is that, in Christ, human beings can be restored to fellowship with God (Romans 5:1–2). This leads to a life in which God’s children pursue glory, honour, and immortality; ultimately, they will share in the eternal glory of God (Romans 2:7–10; Romans 8:17–18, Romans 8:30).2
12 we exhorted each one of you and encouraged you and charged you to walk in a manner worthy of God, who calls you into his own kingdom and glory.
