How can we trust in the effectiveness of Christ's atonement?

Christ's atonement is central to Christian faith and is grounded in scripture's assurance of its sufficiency. In Romans 3, Paul emphasizes the necessity of a substitute who bore the punishment for sin, which is found in Jesus Christ. His sacrifice satisfies divine justice by taking upon Himself the sins of His people, as emphasized in Isaiah 53:5, where He is described as wounded for our transgressions. Thus, believers can have confidence in His atonement, knowing it was designed by God and fulfilled His purpose of redemption for all who believe.
