Why is Christ's atonement essential for salvation?

The atonement of Christ is central to the Christian doctrine of salvation as it addresses the repercussions of sin, which is enmity with God. In Romans 5:9-10, it is stated that through Christ's death, we are reconciled to God, moving from a state of enmity to one of acceptance. This reversal is crucial because it signifies that we are saved from the wrath to come, a wrath that is justly due to our sinful nature. The atonement provides a means for sinners to be restored and to receive the blessings of eternal life and peace with God.
