What does the Bible say about the atonement through Jesus' death?

The atonement through Jesus' death is central to the Christian faith, as outlined in Scripture. Jesus was the Lamb slain before the foundation of the world, chosen to bear the sins of God's people (1 Peter 1:19-20). His death was not for personal sins, as He was sinless, but instead, He accepted the responsibility for the sins of believers, satisfying God's justice (Isaiah 53). This means that when Christ died, He took upon Himself the punishment that rightfully belonged to His people, thus redeeming them from their sins and appeasing God's wrath against sin (Romans 3:25).
