For many pre-schoolers, their favorite question is “Why?”. Asking questions is a natural part of learning about the world around them. Often, adults assume this exploration phase ends about the time kids start school. I personally believe though, that children begin to squelch their oral questioning once they discover it irritates many adults.
As adults, we have learned (hopefully) that certain rules and authorities are to be obeyed. We understand God really does know what is best for us. We have a fairly good understanding of concepts like love, manipulation, anger and many others.
Children and teens are still discovering these more abstract worlds. They are figuring out whom they can trust, what works for them in the short term and hopefully what will be in their best interest for the long haul. They are not just trying to learn the rules, they are trying to understand why they became rules and if those rules are really important.
