The sad thing is that for years I would have dismissed the questions raised by the OP as the result of not having an accurate knowledge of The Truth. I would have had a wry smile that Christendom could not answer these things yet here I was in possession of the full answers.
As the veil has been lifted it is clear that these questions can only be answered by theists by resorting to the supernatural, by claiming that the divine has answers we cannot grasp - a position I now totally reject.
When I speak about these things with my wife now I can sense the pity that somehow I have become blinded by the secular and fallen into a darkness where I can no longer see the blindingly obvious. When mysticism trumps logic then there can be no reasoning.
