How do we know Jesus is God's anointed king?

The Scriptures explicitly announce Christ as God's anointed king, as evidenced in Psalm 2 where God declares, 'Thou art my Son; this day have I begotten thee.' This proclamation as God's eternal Son underscores Jesus' unique relationship with the Father and His rightful claim to kingship. Moreover, Jesus' resurrection and ascension serve as divine validation of His kingship, ensuring that He is appointed to rule not only over Israel but over the entire world. His authority is established by God's decree, confirming that He is the sovereign ruler destined to inherit the nations.
