Well, I'll throw in two cents. I was an atheist, and now I'm a theist. Did I fear death, sin, hell, God, Satan, pain, or insignificance? Did I have some tramatizing event in my life that made me feel the necessity of God? No. Not one of those things. Rather, I came to the logical conclusion that God can and does exist.
I considered what God was in religion itself and what God was to people. God, in the most simplistic form across all the world, is love. God is a personification of a concept common in the human experience. Sure, as you get Bibles and texts and Churches everyone wants to edit it to gain power. People stereotype religions according to which ones are most popular. How did Christianity gain such a ground in the world? Through coincidence, through the alteration by the hand of a man to make it meet his fancy. Take the most precious idea to a person and use it so they'll obey you. The most ammusing line from the Christian Bible must be the one of false prophets. Course, everyone takes that as the final days end of all things warning though the Bible itself is a false prophet added to most recently as the 1600s! As a religion gets more complex and popular and even gains a written language, it is now changed from an original concept. I once spoke to someone who practiced the old Cree ways. They said every religion is one and the same. Gee, I wonder why Christianity's texts preach so much hate? Cause it was necessary to put it on the pedestal it has now.
Is it not useless then to personify a concept common in human experience such as empathy (I suppose the ability to love another as much as you love yourself)? Well, we seem to gain some basic standards for life purely from empathy itself. Don't kill, don't steal, no adultry... the ten commandments are used in law not just cause they're Christian, but rather they seem to apply across times and societies (commandments are an example, but those sort of simple laws that aren't obscurely written down in a few passages seem to follow a pattern of 'don't harm everyone').
God's a word. Make it into whatever you want. If there's a million religions, there's 6 billion gods. Could do the actual percentage on that, but you get the point.
