If you are taking the standard judeo-christian view of Jesus, he is part of the holy trinity(which is basically quantum polytheism), along with the Father, and the Holy Spirit. As such "God's" plan is really *his* plan, and the Holy Spirit's plan. Therefore as they are infallible entities that form a sort of Voltron supergod, and they know what all decisions have or ever will be, they do not "allow" anything. It was God's plan. Do you suppose Jesus(who is god), or Pontius, or whomever, deny gods will to sacrifice his son(really him), to absolve man of the sin he invented, to save them from going to a hell he created.
Why not just snap his cosmic fingers and be done with it. No blood sacrifice necessary.
You quoted me, but nowhere in that quote did I mention "fixing", just the word 'modification' which would encompass both fixes, and changes, neither of which would be compatible with the god I described previously(the theist, infallible).
