What does the Bible say about the atonement of Christ?

The doctrine of the atonement, as revealed in Scripture, highlights that Christ's sacrifice on the cross was both complete and particular. His atonement was not a generalized offering but a specific payment for the sins of His elect, as stated in passages like Romans 3:24-26 and Hebrews 9:26. These texts affirm that Christ's work ensures the justification and glorification of believers, solely through His righteousness, effectively rendering any human effort to attain righteousness unnecessary. By magnifying the totality of Christ's redemptive work, we see the essence of the gospel: that Christ Jesus came into the world to save sinners (1 Timothy 1:15). As such, any notion that salvation is merely made possible by Christ's death instead of being fully accomplished undermines the glory of God and distorts the true nature of the gospel.
