How do we know Christ is our peacemaker?

Jesus Christ is referred to as our peacemaker because He has made peace between God and humanity by His sacrifice on the cross. Colossians 1:20 states, 'And having made peace through the blood of his cross.' By dying for our sins, He paid the penalty required by divine justice and resolved the enmity that existed due to our sinfulness. This reconciliation allows us to enjoy a restored relationship with God, where we transition from being enemies to being children of God, deeply rooted in His love and grace.
