I always hear people (who are usually criticising someone, sometimes me) saying, 'but we have to have faith like a child' - which apparently translates into - 'DON'T QUESTION! JUST OBEY!'
Umm...apparently these people have never spoken to a child.
'Why?' is one of their favorite words. (Along with 'no', but that's another matter)
My grandmother swears my first word was 'why', and that it'll probably be among my last, too. I question things, endlessly. Beat a dead horse, whatever. I don't always understand the explanations for things, I just want to know that there is one, and that someone else knows it and I assume that eventually I will understand it.
My grandmother loves telling this story:
We were in the car, driving somewhere, and I asked her a question. She can't recall the question, but she does remember that she didn't know the answer, and so proceeded to make some long answer up. At the end, she says I said, 'Grammy, if you didn't know the answer, just tell me.'
Kids are *always* questioning. It's how they *learn*.
So I don't see any problem with questioning everything, up to and including God. The problem with kids is, eventually we realize that adults don't have all the answers, and the power in the relationship begins to shift, little by little. The thing with God is, He does have all the answers (whether He shares them with us or not, and whether we understand the answers we get or not), so there's no fear of the power structure shifting.
