Why is the doctrine of atonement important for Christians?

The doctrine of atonement is foundational in Christian theology because it underscores the significance of Christ's sacrifice in providing redemption. Romans 4:7-8 states, 'Blessed are those whose iniquities are forgiven and whose sins are covered.' This denotes that through His atoning work, believers are restored to a right relationship with God. Understanding this doctrine instills hope and assurance, as it highlights that there is no sin too great for the cleansing power of Christ's blood. It reinforces the gospel message that salvation is a gift of grace, free from human merit.
