When discussing our faith, what should we do with difficult questions? Ask them.
This was the way with Jesus. He asked over 300 questions in the Gospels. On the other hand He was asked around 180 questions. (I haven’t counted these up myself, I’m relying on the work of others, including Randy Newman whose book Questioning Evangelism is excellent.)
How many questions do you think Jesus answered? In terms of a direct answer, I count three (Matt.22:36-37; Luke 11:1; John 18:37). Maybe you can identify more, but here’s the point for now: the vast majority of questions which Jesus was asked did not so much provoke answers, they provoked further questions. That’s a challenge for all of us.
