What I would like to point out is that He did it in cooperation with Him. He does not violate or impose. I can't remember the Biblical reference off the top of my head, but in the NLB Paul refers to us as "cooperators with Him". He does not do magic tricks but in all that He does He seems to work teleologically, not randomly. Of course He heals and not we! A more cogent concern is that we so seldom ask!
