You can not teach every kind of book the same way. Different teaching methods for different kinds of literature.

The format should drive the content and the structure of your lectures. Poetry uses symbolism, imagery, and hyperbole to evoke responses. You can't find straightforward theological statement like you can in Narratives. Narratives are God’s Revelation to humans, but Lamentations, for example, are human's response back to God. The way you teach poetry needs to be different.
