<p>Letter's of Peter are two ancient letters written by Jesus right-hand man Peter Simon. </p><p>In Peter's first letter he tell his followers to live good lives and follow the law. He admits that it's a shame that their good deeds are not rewarded by God but that the reward will come eventually perhaps in the next life.</p><p>In Peter's second letter he suspects that he won't live much longer and he warn people against switching from Christianity to another religion as that's a one way ticket to hell. </p>
