How does Christ's reign relate to the gospel?

The reign of Christ is integral to the gospel message, as it establishes His authority over sin and death. As stated in Revelation and highlighted in Psalm 93, Jesus is King of kings who sits on His throne to intercede for His people. His sovereignty guarantees that salvation is not merely a possibility but a certainty for those whom the Father has given to Him. This truth encourages believers to embrace the gospel as good news, knowing that Christ's reign assures their security and the fulfillment of God’s plan of redemption.
