How do we know Christ is King according to the Bible?

Psalm 2 affirms the kingship of Jesus, stating, 'Yet have I set my king upon my holy hill of Zion' (Psalm 2:6). This declaration confirms that Jesus is God's appointed king, highlighting His sovereignty over nations and individuals alike. Throughout the New Testament, Christ's kingship is recognized not just in His title 'King of the Jews,' but in His authority over life, death, and all creation. Even those who oppose Him, consciously or unconsciously, serve His ultimate purpose, confirming that He reigns supreme as both Savior and Lord. Ultimately, His reign offers His people protection and security as they trust in His sovereign rule.
