How do we know that Christ's reign is true?

We know that Christ's reign is true because He has been exalted by God the Father; His resurrection serves as a testament to His divine authority and power. Scripture confirms that God has given Him all power in heaven and on earth, encapsulating His rule and reign over all creation. Moreover, His eternal covenant with the Father to save His people ensures that all whom the Father gives Him will be drawn to Him, guaranteeing His kingship is not dependent on our actions but on His sovereign will and grace.
