Christ has stood in the place of the true Christian. He has become his Surety and his Substitute. He undertook to bear all that was to be borne, and to do all that was to be done, and what He undertook He performed. Hence the true Christian is a justified man.Old Paths, Chapter 8
Again, we argue for the doctrine of the atonement, from our reconciliation with God, which Christ by his death has procured for us. Since that reconciliation supposes the making up of the breach which sin had produced between God and his creatures, this could not be effected without the removal of a twofold barrier, by a satisfaction. On the part of God, his justice must be satisfied, and on the part of man, the guilt of sin must be removed by suffering the punishment due to it. The Apostle Paul, everywhere, teaches us that Christ procured for us such a reconciliation (Romans 5:10; 2 Corinthians 5:18-19; Colossians 1:20-21).The Substitutionary Atonement (p 45-46)
