How do we know God's glory is revealed in the salvation of His people?

God's glory is fundamentally tied to the salvation of His people, as articulated in the sermon. The glory of God is revealed through Christ's redemptive work, which is the ultimate expression of His love and justice. In John 17:1-2, Jesus speaks of being glorified as He gives eternal life to those whom the Father has given Him. This mutual glorification between the Father and the Son emphasizes that salvation is not merely a theological concept but a reality that showcases God's attributes. The shepherds in Luke 2 were the first to hear this joyous message, and their subsequent proclamation illustrates that salvation brings glory to God by demonstrating His mercy, power, and faithfulness throughout history.
