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 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
Literary genres, rhetorical function, and learning domains in homiletics
The impact of sermonic form and literary figures on audience attention
Crafting sermon series from scratch
Crafting sermon series by implementing texts from the Revised Common Lectionary
