How do we know that Jesus is sovereign?

The sovereignty of Jesus Christ is affirmed in the biblical narrative, particularly in Acts 17 where it's declared that earthly powers, including Caesar, are under His control. This theme runs through passages like 1 Corinthians 6, where He is called the 'blessed and only potentate,' and in Luke 2:1, where the actions of Augustus Caesar are shown to fulfill God's prophetic purposes. His sovereignty ensures that even the choices of men ultimately serve the divine will, demonstrating His kingship over both the living and the dead.
