At church this morning, a boy - I would guess 6 or 7 - was standing on the top of the pew in front of his dad. His dad has the little boy's hands, and then the boy just threw himself forward.
He hung with his head down, but if his dad lost his grip, the little boy would have somersaulted and crashed into the next pew.
That thought didn't even enter his head I'm sure. He had such faith that his dad would never allow anything to happen to him that he knew he could flip around and be a daredevil without fear.
Put an adult in the same situation, and I would 99% or more of us would not trust another person enough to fully throw themselves forward and trust someone to grab them. Most of us don't even trust God like that. We should though. We're encouraged to act like little children, and that means sometimes just trusting that God will catch us when we take a leap.
