Atheists, can you understand this?

Personally I'm agnostic, but I believe it's the belief in God most atheists don't agree upon. Not exactly the morals of common good and such that the Bible tries to impose on it's readers. Most decent people still have those basic morals and may not see certain things Christians like yourself see as sin to be sinful but would agree on murder being heinous and a horrid act to commit. I'm very happy for anyone who can definitely believe there is a God and believe in heaven. I would believe it must be good and give some sort of optimism to life to think your body dies but your soul lives on.
