"Loved, lost, and finally found! The life and ministry of Rev. D. Otis Teasley is quite a story, actually two stories. The first is prominent in the early life of Church of God Movement and the second has been a major mystery until now. Skilled historian David L. Neidert has exhaustively uncovered the mystery, and done one more important thing. He’s made clear that the complex history of this particular reformation movement, and of any such movement, is understood better when considered through the avenue of detailed biography.

I Am the Lord’s is two stories. It’s a wonderful testimonial song of Teasley’s composition, sung with joy in the Movement for generations. It’s now also the title of a superb and highly documented biography of Teasley that throws new and sometimes uncomfortable light on aspects of a church’s early life. The Church of God Movement and the Holiness Movement in general are clearly in David’s debt. May other such works soon come into being!"
