How does Jesus' role as the angel of the covenant affect salvation?

Jesus' role as the angel of the covenant is pivotal in understanding how salvation is accomplished. He stands as our representative in the covenant of grace, having promised to fulfill all obligations required by God's law. His death on the cross was not just an act of love but a necessary fulfillment of the demands of justice—death for sin (Romans 6:23). By His obedience, He satisfied God's requirements and made reparation for our transgressions, allowing us to be reconciled to God. This covenantal framework provides assurance to believers, emphasizing that our salvation is secure in Christ's accomplished work, not dependent on our efforts, but entirely on His grace.
