How do we know Christ's death made peace?

Christ did not die merely to offer peace; He died to make peace. He took upon Himself the enmity caused by sin, thus fulfilling the requirements of divine justice. Hebrews 13:20 emphasizes that the God of peace 'brought again from the dead our Lord Jesus', showing that His resurrection was the confirmation that peace was accomplished. This underscores that through His death and resurrection, Christ dealt effectively with sin, allowing us to be reconciled to God and thus gain true peace.
