So according to the article, is order for us to exist temporally, we must exist eternally somehow. For that to true, we also must exist 'before the world began". That's an argument for the pre-existence of souls. In a way, this makes sense. especially when factoring the concept of evil. perhaps evil only exists in the temporal world, but is absent from the eternal. How this can be, I do not know, but it does allow evil to exist without thwarting the overall plan and dishonoring God by saying H is the source of moral evil. It also supposes that we are even now existing in eternity right now as we speak, which is mind-boggling to imagine.
