How do we know that Christ's sacrifice brings peace?
Answered in 2 sources
We know Christ's sacrifice brings peace because Scripture explicitly states that He reconciled us to God by His blood on the cross.
Colossians 1:20 declares that through Christ's sacrifice, peace was made by the blood of His cross. This act of atonement means that the conflict resulting from our sin has been resolved. Romans 5:1-2 reinforces this truth by affirming that justification by faith grants us peace with God. The consistent message throughout the New Testament underscores that Christ's sacrificial death is the foundation for our peace, thereby alleviating our guilt and shame before a holy God. Therefore, the peace we receive stems directly from Christ's accomplished work on our behalf.
