We welcome input from theists like yourself, Andrew. However, if you just plan on posting long walls of religious text without responding to our comments and questions, nobody will benefit. And you will get teased unmercifully by our snappy atheist repartee.
You are absolutely right about this: you will have difficulty convincing us that your god or hell are real, and therefore we have no intentions of repenting for imaginary sins. So you can save your bandwidth on those topics.
