The highest level of your will, the center of your intentions, will be fixed at the time of your death. The Christian eternity is not an infinite amount of time but the absence of physical time. The pursue of nihil is Hell.
Those are concepts that wholly absent from the early christian writings, including the gospels, even flat out contradicting them. Your philosophical speculation is as good as anyone else's. And it doesn't meet the challenge anyway: Since you claim that god creates every soul at the moment of conception, then the destiny of each soul rests under his wing. Including abandoning such soul to a supposed hell of nihlism. Again, why would a god of love and justice do that? After all, that soul didn't ask god to come to existence.
