No, God will not punish you. More apt to say, God most likely will not help you with that attitude. He will simply allow you to continue along as you are until you drop fully dead and silent and far from his ears forever. I do realize how harsh that sounds, and I do not mean to be harsh, truly. But that is the way it is, I would not want to decieve you with either stories of heaven or hellfire

Lest of course you reach out your hand with your last breath and say, abba, father. It's been known to happen, those last minute concessions. Where it gets you I really don't know though but of course the possibilty always exists.
