I've taught Bible, theology, and homiletics to many people, in many places, over many years. Some of the content that I enjoy teaching about the most, includes:

Bible overview
Bible as literature
Bible as theodrama
Nature and function of the Bible
Books in the Bible, with particular interest in wisdom, gospel, and story genres

Apology for reimagining a good Christianity
Theology as non-violent
Theology as theopoetics
Affective theology
Gospel as empire subversion
Perspectives on universalism
Church as a witnessing community

Introduction to homiletics
Biblical literary figures that hold attention and make meaning
Biblical genres and their relationship to rhetorical functions and learning domains
Crafting sermon series from scratch, the church calendar, and the revised common lectionary
