Why is understanding Christ's authority important for Christians?

Christ's authority is underscored throughout Scripture, particularly in Revelation 1:18, where He claims, 'I have the keys of hell and of death.' This statement reveals not only His dominion over life and death but also reassures believers of His sovereign control over all circumstances. For Christians, knowing that Jesus holds ultimate authority instills confidence in salvation, as He is the one who reconciles us to God through His death and resurrection. Indeed, our hope rests in the fact that He is not only our Savior but also our King, reigning in power and majesty, ensuring that nothing can separate us from His love.
