I myself was once religious, but not anymore, because it just didn't make a whole lot of sense to me.
Many non-believers on this forum attribute their disbelief to the fact they consider God to be a sadistic individual. The world was never fair, so why should God be? He seems to pick and choose who he works his divine powers on, and if you're not one of those people blessed with divine protection, tough luck. There's also no way to "influence" God into making him choose you. It's akin to an abusive relationship with a boyfriend or girlfriend, except very hyperbolized. You pray to God and put worship him in hopes that you find some sort of comfort or he grants you some sort of miraculous protection. If you are one of those chosen ones, you'll be euphoric and preach your faith to others, but if you're not, you're left heartbroken and in despair, wondering where you went wrong. It's just a whole lot of trouble I'd rather not involve myself in.
I won't be one to challenge your beliefs or disrespect them, but they're just some things to consider when making the decision to let God influence your decision making, be it moral or otherwise.
