What does the Bible say about the power of Christ's endless life?

Hebrews 7:16 refers to Christ as being made after the power of an endless life, contrasting His eternal priesthood with the temporary nature of the Levitical priesthood. This signifies that His life is not only everlasting but also filled with divine power. Christ's life encompasses both past and future eternity, and through His death and resurrection, He secures salvation for believers, thus activating the life-giving power essential for their redemption and sustaining them in faith. This endless life is pivotal as it guarantees that those whom Christ has redeemed shall never perish, affirming the security of the believer's salvation in Christ.
