It's true that some of the Bible is unimaginably hard to understand. Save them for when you have studied enough to understand non-euclidian geometry, quantum mechanics, and women. The parts you "bet your eternal life on" are simple enough for a child to understand. In fact, children are much better off because they realize they can't handle things by themselves. Children, at least are smart enough to say, "Daddy! Help!"
"Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these"
