Lesson 6 of the Old Testament Gospel Doctrine manual seems like a difficult lesson to me. It covers both the story of Noah and the flood as well as the story of the tower of Babel. The lesson combines these disparate stories under the very general topic of worthiness and avoiding the evils of the world, which may not give most teachers much to work with. While I can’t really tell teachers where to go with this, I did find a poem that also addresses these stories (and a few more) in a very general way.
I love the first lesson in the Lorenzo Snow manual. It seems like Snow’s love of learning is second to none among latter-day Prophets. And his statements about learning are wonderful: “Though we may now neglect to improve our time, to brighten up our intellectual faculties, we shall be obliged to improve them sometime. We have got so much ground to walk over, and if we fail to travel to-day, we shall have so much more to travel to-morrow.”
