Sorry. This really isn't the same thing. "fall out with God" happens all the time. The "back-slidden" Christian.
Rejection of God is quite another. Within OSAS you either DO believe that Jesus is who He IS, or you were NEVER "saved".
Will a saved person have doubts? Almost certainly. Sin? Yep. Become "less religious" almost to the point of agnosticism? It could happen. Every REALLY believe "Jesus Christ is NOT God"? I think it's possible, you shouldn't.
Well if you reject then that's definately a falling out IMO lol:') Stop preaching to me about OSAS,ok? You don't believe it so you are just talking the talk. You aren't a liar. You know everything you think you need to know but you don't believe, really believe in it, right?
