There is a sad but true joke about those that believe in God, but expect Him (or Whomever) to only express Himself through miracles. It goes like this:
A man is on the roof of his house, with floodwaters rising all about him. He is offered help by a balloonist in a balloon, a helicopter, and a powerboat. He refuses all of the offers, claiming that
he believed that God alone would save him. He ends up drowning, goes to Heaven, and asks God why he was allowed to drown. God's response: "Well, I tried. Who do you think sent you the balloonist, the helicopter and the powerboat?"
The point should be painfully obvious God does not need to violate His/Her/Its/Their laws in order to be real. God does not have to be spectacular in order to give us what we need. And God, above all, does not need any so-called followers whose alleged "faith" depends upon putting God to one or more tests.
That latter blasphemy is exactly what faith-healing believers do. And, when they subject children to the tortures of faith-healing, they become doubly heinous. Parents of children like the one in this story can't be punished enough. At the very least, laws should be changed everywhere to make that punishment possible.
