These are things I've written through the years. Some are more detailed and academic than others. Many are notes from classes I've taught at church. If I failed to credit a source of wording or ideas it is because I did not cite the source in my notes and no longer remember it.
I add to the collection periodically. If anything here is helpful to you, I would be encouraged by knowing that. Drop me a note at firstname.lastname@example.org.
Some of my lessons are available off-site.
