How do we know that Jesus is both Lord and Savior?

The dual role of Jesus as both Lord and Savior is a central tenet of the Christian faith, firmly established in scripture. This revelation is evident in Jude's acknowledgment of Jesus' lordship and redemptive work. Acknowledging Jesus as Lord means recognizing His authority over all creation—including the authority to save and redeem His people. This is not merely a title but an affirmation of His active role in the sovereign plan of salvation. Furthermore, Jesus' efficacy as Savior is evidenced by His completed work on the cross, which He accomplished for the sins of His elect. The recognition that He is both Alpha and Omega, as the beginning and end of all things, underscores the necessity of seeing Him as the ultimate source and sustainer of salvation, as laid out in Jude's epistle.
