How do you get people to wrestle with the Bible, not just nod their head without thinking?

One way is to show them they assume the opposite. Lead them down the path of thinking A only to show them God says B.

For example, if they were a shepherd and they lost one sheep, would they really “leave the 99 in the open field” (vulnerable to lions and bears) to find one sheep… One sheep that’s probably already dead, or will turn up soon on its own anyway!?! People don’t go looking for lost coins!! They don’t celebrate when their fortune-wasting son returns!!!

Once people realise they don’t actually agree with the assumptions in the bible, that’s when REAL thinking and character development take place.

Before you teach your next thing, ask yourself whether you need to show people they don’t actually believe it.
