Well, I have always thought there was much more to Christ's ordeal (i.e., that he was more than a stand-in) than what you have told me, but I wasn't sure of my interpretation. I thank you for responding to my question, but, although I'm not at all sure, still I think there's more to Christ than his being a mere whipping boy for humanity.
Luke 4:18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, 19 To preach the acceptable year of the Lord.

It's also best if you read the what,why,when yourself directly also.
