“Let us ever glory in the cross of Christ; let us regard it as the source of all our hopes, and the foundation of all our peace. Ignorance and unbelief may see nothing in the sufferings of Calvary but the cruel martyrdom of an innocent person: faith will look far deeper; faith will see in the death of Jesus the payment of man’s enormous debt to God, and the complete salvation of all who believe.”
Day by Day with J.C. Ryle “The Cross” p.48
For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past, for he was looking ahead and including them in what he would do in this present time. God did this to demonstrate his righteousness, for he himself is fair and just, and he declares sinners to be right in his sight when they believe in Jesus.
