How do we know that Jesus' sacrifice provides true peace?

The peace that Jesus brings is rooted in His sacrificial death on the cross, which reconciles sinners to a holy God. Romans 5:1 states, 'Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.' This peace is not merely the absence of conflict but a wholeness and reconciliation that is only possible through faith in Christ's redemptive work. His role as the messenger of peace, coupled with His meek demeanor as He enters Jerusalem, underscores that true peace is obtained not through works, but through faith in Him who was sent to save His people from their sins.
