I wonder how many of those miracle stories ended with the whole family getting killed in a car wreck a month after their prayers were answered.
That's because the dad was driving the car and the dad was having a momentary lapse into impure thoughts, so Jehovah lifted his protection and the demons wrecked the car. Or the dad had the classic rock music station playing on the radio. How can you expect Jah to protect with you with Led Zeppelin cranked up to number 3 on the volume?
The other miracle stories that ran amok? I think the biggest cause of those tragedies is that someone was thinking rebellious thoughts against the local body of elders, tantamount to blasphemy.
