What would it take for you to become any other of the hundreds of different religions? What would it take you to not believe in your god? Why do you choose to worship one god instead of another? Why do you laugh at the idea of someone believing in Zeus or Poseidon when your god may be viewed in the same light years from now? I personally don't worship because it seems demeaning to me and offensive. (Why should I live my life in fear of doing something wrong and be under the constant scrutiny of some higher being hoping I get his blessing to be let into some pearly gated sanctuary)
