Good quote here:
I have read some explanations on the death of our Redeemer and Saviour that represent it as a work that Christ did to appease the wrath of God, or as a ransom that Christ paid for man to free him from the bondage of Satan. But I believe that the wrath of God upon sinners and their bondage to Satan are moral images that aim at manifesting the true dimension and the deep contradiction between sin and God. The animal sacrifices that the Children of Israel offered to God expressed man's realisation of the distance that sin creates between him and God, and his conviction that death only can atone for sin, since sin is an uttermost offence against God.
This is from Rishawi's book A Struggle that led to Conversion. It is interesting to note how an Egyptian Christian, from an ex-Muslim background, accepts the doctrine of vicarious atonement, while rejecting the evangelical theory of penal substitution. Good for him!
