How do we know that Jesus is the King?

The declaration in Psalm 2 that God has set His King upon the holy hill of Zion demonstrates Jesus' appointed kingship. Throughout scripture, especially in the New Testament, we see His authority over creation, powers, and even death itself. When the preacher emphasizes that Jesus, referred to as the King of Glory, took the battlefield on behalf of His people, it illustrates His role as a servant King, contrasting the typical image of kings who demand service. Jesus’ resurrection and the title 'King of Kings' serve as final affirmations of His eternal authority and reign.
