Here's My Humble Opinion..
The Idea and philosophy behind there being a God is a good one. It's the man-made 'Conditional Modifiers' That form the different religions which divides and spoils the concept.
I hear what you're saying,.. "What?"
Simply, I believe in God and the 'One' true message common to all religions.. Peace, Love and Kindness. It's not rocket science, broken down to the simplest terms it's basically "Do unto others as you would have them do unto you." Oh, and the "Tho shall not kill" thing is simplistic too, I mean, there is one certainty in life, we will all die. So what is the point of wasting time and energy on something that is inevitable.
There are two things and two things only that prevent humanity from becomming the sanctuary (aka: Eden) that we all wish it was. These two things are 'Religion' (not God, but the man-made rules on how to worship him) and 'Boarders'. Until we can unify these two things One God, One race, we are doomed to live in strife.
Nuf said, Cheers!
