First... do you believe in God or not?
If yes, then whichever religion or God you follow should probably give you guidance. But I'm assuming that you no longer hold belief in God...
So, the issue then is: if it turns out you are right, then the worst that can happen is... nothing.
If it turns out you are wrong, and that God does exist, then it rather depends on how this God thinks of and treats people who didn't believe in him. And the question then is how you could find out, given that this God presumably hasn't given enough evidence to convince you that He exists, let alone tell you how he will treat you should you not believe in him.
Pascal's Wager would have you believe in God purely on the gamble that if you do and you're wrong then you lose very little, but if you're right then your reward is eternal life in heaven etc.
But then the question is whether a God would reward someone for believing purely to hedge bets.
My own advice, for what it is worth, is that one should not come to belief or non-belief on what you can potentially gain or lose, but on whether you do truly believe or not.
I do not have a belief in God, and no matter what rewards I am offered or what the risk of non-belief is, I could not force myself to believe... I could at best offer lip-service.
If I am wrong, and God does exist, I guess I can only hope he judges me on aspects other than belief.
