Infinite Punishment for Finite Sins?

You make a good logical point. But if you hoping for a coherent well thought out answer from a Christian I think you'll be waiting a long time. Its not that all Christians are stupid I think that there is a few smart ones. Its more that their religion is so comforting to them their not willing to let it go at any cost. The idea that there is no real plan or purpose to human existence scares the hell out of them. So at some unconscious level, if they feel that an argument is becoming too convincing, the logical part of their brain shuts down. The only Christians that likely to answer your questions are the ones that don't really grasp your point, so they don't fear it.
