The greatest comfort we have in this life is that our sins have been forgiven, forever. Christ has purchased for us God's full forgiveness of sin. Someone always has to pay the price for forgiveness, but price we had to pay was paid on our behalf at Calvary. Let us rejoice in the forgiveness we have in Christ Jesus!
