Zion produces an audio podcast called "A Stone in Zion."
Every week the podcast features the sermon text and the sermon itself.
Before the sermon Pastor Kesting will either give a brief introduction to the sermon or will interview a guest. Usually the topic of the interview will have something to do with the sermon that follows.
