I have observed the same thing.... people who do not believe exactly the way the organized church seems to want us to believe.... or difine God the way they want.... yet we see people who have a concept of God as the understand him and live incredibly loving, authentic and giving lives... we see them blessed.
I beleive there are universal principles that God has set in motion and whether or not we give God specific recognition for them.... they still work.
With all of that said, my conclusions keep steering me to recognize God as Jehovah as the Bible describes him. And although I can't quite get in full agreement with the outlooks and standpoints of many Christians and churches, I can't see that Jesus was not who he claimed he was.
His teachings are amazingly valid in my life. The Bible is amazingly true. It is funny it took a journey away from "God's People" (as so many call themselves) to come to believe this on the level I feel I do.
