Andrew, your argument seems based upon the faulty premise that if there is a God, he should do whatever we want him to, and he should do it now and he should do it without charge. (Sort of like how stereotypical left-wingers expect government to work, but I digress.) The problem is, the Bible in both the Old Testament and the New Testament makes it quite clear that Elohim does not work that way.
That wasn’t my argument. Besides, making it clear he ‘doesn’t work that way’ is the eternal cop out.
My argument was that if God ‘heals’ why do his abilities appear so limited?
As I said, your argument is that if God doesn't make use of the abilities you want him to use, He must not be God. As you point out, we can do things now that would have been considered miracles in ages past. Perhaps God wasn't interested in keeping us from learning how to do them by doing them for us? Perhaps that explains why he doesn't do other things your "I want it all and I want it now" philosophy demands he do?
