In this episode Timmy talks about his evolved view of what he had been taught to believe his whole life, and that is that "Jesus is the only way". And what that means is that the only way you can get to Heaven (if Heaven even exists) is to believe in Jesus, and if you don't believe in Jesus then you are choosing to spend eternity in Hell. This also means that all those who are Hindu, Buddhist, Muslim, Jewish, or any other belief system are going to burn in Hell forever and ever also. Timmy could no longer believe this, and he talks about why.
