Why is Christ's atonement significant for Christians?

The significance of Christ's atonement cannot be overstated in sovereign grace theology. Romans 5:18 states, 'as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men.' This encapsulates the doctrine that through Jesus Christ's perfect obedience and sacrificial death, believers are given a righteousness that is not their own. This imputed righteousness is what justifies the elect before God and secures their eternal life. Furthermore, it emphasizes the grace of God, where despite humanity's total depravity, redemption is fully realized in Christ. His atoning work is the cornerstone of the Christian faith and critical for understanding the grace of God offered to the chosen.
