But now, I find that doing the reading makes me a better teacher and saves effort in the long run. For example, in my Balaam lesson I referred to Colossians 2:15 and how by the cross Jesus made a public spectacle of evil powers. That didn’t come from any lesson guide or cross-reference notes; it just came to me as I was thinking about Balaam’s embarrassment—and because a few months earlier, I’d reread Colossians.
