Why is the concept of Christ as king important for Christians?

Christ's kingship assures us that He reigns over all creation, providing hope and security to believers. In 1 Samuel 21, the narrative of David foreshadows Jesus as the true King who triumphantly defeats His enemies. This is further emphasized in Revelation 19:16, where Jesus is referred to as 'King of kings and Lord of lords,' affirming His authority over all earthly powers. For Christians, recognizing Christ's reign means trusting His sovereign plan, knowing that He works all things for our good and ultimately leads us to victory in Him. His kingship brings confidence amid trials and assurance of justice in a world that often seems out of control.
