I was raised Protestant, but later attended many different Christian churches. Every single one sooner or later did something that turned me off from attending them. (Usually it was bigotry.)
I had a personal religious experience (which I don't care to share - sorry). Afterward I studied the Bible (in my estimation a flawed work of man, but a good study guide as long as you don't take it too seriously). I also looked into the Koran and the Torah, plus a few other philosophical works.
I developed my own personal religion. I base my beliefs on what feels right to me and a core of the golden rule. I'm still at base a Christian, but my belief system encompasses all religions. I think they're all correct.
I believe God is ALL. He/She is everything, all beliefs, all thoughts, all matter. God is the universe and everything within it. You are part of God and God is part of you.
God doesn't care how you worship, or what you were raised to believe. God cares if you're a good person.
There's more to it, but my person belief system is uncomfortable with proselytizing, which this is approaching.
