Someone emailed me and asked me to post this question on the blog. I think it is a worthwhile question and, considering the reaction in class, many of you seem to think the same. I have cut a pasted the email below. Enjoy.
"If someone is already in a relationship to God, and sin does not take the person completely out of the relationship, and taking the steps of being reconciled with our brother is enough to qualify us for things like Sunday worship and communion and being in fellowship with God again, what is the place of Christ's sacrifice on the cross for sin?"
