How do we know that God's way of forgiveness is through Christ?

The assurance of forgiveness being through Christ is rooted in the scripture that highlights His sacrificial death as the only means through which our sins can be forgiven. As stated in Luke 24:47, the remission of sins is to be preached in the name of Jesus, signifying that no other name can provide salvation or forgiveness. Ephesians 1:7 reinforces this by declaring that in Him we have redemption through His blood, the forgiveness of sins. Thus, Christ's death is central to God’s plan of forgiveness, demonstrating that it is through His atoning sacrifice alone that we find redemption.
