Honestly: I am very reluctant to enter this thread, because it is inviting all kinds of militant views from either side to start clashing again.
There is however one dilemma, which has to do with God creating all and everything and being omnipotent.
If God indeed is the source of all, omnipotent and therefore not bound by rules, then how can one trust His word? If God (akin @LostInParadise, reference to Euthyphro) is the source of morals, then he is not bound by them, so He can chose to either lie to us or not. Whatever he’d chose to do would be right. If He is therefore the source of morality, then why trust the bible, Torah or Qur’an?
If He isn’t the source of morality, then why don’t we look for the true source of it?
So…
“If one believes that God indeed is the source of all, including morality, and (therefore) not bound by rules, then how can one trust His word?” (If He is bound by rules, where did those rukes come from?)
