How do we know that the atonement of Christ is true?

The atonement of Christ stands as the cornerstone of the Gospel message, as articulated in passages such as Hebrews 2:9, where we read that Jesus was made lower than the angels for the suffering of death. His vicarious sacrifice ensures that the wrath of God intended for our sins was laid upon Him instead. The sinless one bore our sins and was punished in our place, a doctrine that is supported throughout Scripture, affirming that our salvation hinges on His completed work on the cross. As believers, we rest in the assurance that the atonement is central to our faith and something that even the angels commend, as described in 1 Peter 1:12.
