Venden points out that the atonement must have been complete at the cross—the sacrifice was sufficient. When Jesus died for man's sin it was enough to purchase man's salvation and man cannot add anything to it. Yet, the atonement involves more that just sacrifice. The process of redemption, the restoration of man's broken relationship to at-one-ment with God, was not completed at the cross, else there would be no more sin or sickness or pain or sorrow or separation or battered children or hospitals or funeral trains or tombstones or broken hearts. It is the winning of men back to a love relationship with God that is not yet completed.
