The reason, imo, that God does not, more often, heal cancer is that he knows that unless one changes one's diet and lifestyle which causes cancer, if healed one will just keep doing what caused the cancer in the first place.
So then we should see an insane amount of miraculous cancer healing in children who never had a chance, right? It's not like they chose their own diet. So every single child with cancer should be expecting a miracle by your standard. Or has god turned his back on them too, as you claim he does for people who don't follow a strict diet and healthy lifestyle?
