The Bible lays down the pattern of asking questions as a way of finding out about Jesus and for growing in a relationship with him.
In Deuteronomy 6.20 and Exodus 12.26 it shows how God urged people to live in such a way to deliberately provoke questions from their children so that they could learn about what God had done. And in Colossians 4.6 and 1 Peter 3.15 Christians are encouraged to be ready to answer people's questions about Jesus. It is clear that questioning is to be encouraged because it shows curiosity and a hunger to learn, a desire to know God.
Sadly, we live in a culture where questioning is often seen as something negative. By not giving people the chance to ask questions, by seeing it as rude or an uncomfortable challenge we discourage learning. The young people in our groups are in a position where they are learning not to ask questions. They remember all too clearly the times when their questions have been laughed at, given an inadequate answer, or simply dismissed. And they rarely see adults ask questions, or admit to not knowing everything.
