My older brother has a 4 year old son. He has a wild imagination and is frequently freaked the hell out at night. So my JW brother naturally tells him that Jehovah will protect him.
When this statement doesn't appease the fearful child he will use a statement along the lines of "Do you question whether Jehovah can protect you?"
It's an interesting question because the Watchtower uses this reasoning with it's members as well. Of course Jehovah is synonymous with "faithful and discreet slave."
The WT treats it's members very much like children afraid of the dark. They give them a fake solution to their problems and then if it is questioned they guilt them into believing it.
