How do we know Jesus is the eternal King?

Jesus' kingship is eternal and not bound by time. The Gospel of John (1:1) explains that 'in the beginning was the Word,' highlighting Christ's existence before creation. Additionally, Scripture such as Daniel 4:34 illustrates God's unending dominion, reinforcing that Jesus, as God incarnate, embodies this eternal kingship. His ability to lay down His life and take it up again (John 10:17-18) further underscores His authority and kingship, making it clear that He reigns not by human appointment but by divine right as the sovereign Lord over all eternity.
