Given your choice of “churches”, Mike, maybe the better question you need to ask is why did Jesus have to die when he could have stayed on earth and cured everybody of everything? Just show up and Jesus would fix it!
Yet there are some who seemingly get cured before going to Heaven. And the dividing line is suspiciously as to what the human body can fix on its own and what it can’t.
Don’t really understand the import of this question. Only answer I can have for that is God obeys his own laws, and natural law is one of those. There are those maladies that are incurable in nature, though we are given the intelligence to find cures for them. That’s our business, not God’s.
If God allegedly does answer prayers, and if the ones whose prayers get answered have ailments the body can fix, why is it that he can’t or won’t answer the prayers of the people who have ailments the human body can’t fix?
Who says he doesn’t. Although the cure might not be physical. Your question has great merit, if you consider God merely a great cosmic vending machine; you know, put in the coins (prayers), pull the handle and out comes the expected goodies. Unfortunately, the God we know as Catholics (other Christians and Jews and probably Muslims) doesn’t work like that.
Why is God so stringent on only working one side of that dividing line?
Not sure what side of the dividing line you are talking about. Why does God only cure the curable; well because it is curable, but then I don’t think God had much to do with it as did the human body itself and the medications man has found to cure those things that are now curable (although once they weren’t). If you are talking about curing the incurable as happens on rare occasions, I’ll have to ask him when I meet him.
My original post to which you asked these question referenced our Catholic belief in the perfection of the life to come in His dimension where, as Jesus said, “eye has not seen, nor ear heard, the wonder God has for man…” If you don’t believe in that God or that dimension, I’m sure my answers seem silly.
