Two Wednesdays ago I taught on Christian unity. Later I published a devotional piece based on what I taught. See here. I made use of F.G. Smith's "What The Bible Teaches" and Arlo Newell's "The Church of God as Revealed in Scripture."
I am still reading Smith as well as Adam Miller's "An Introduction to the Old Testament."
Last Wednesday snow prevented the Church from meeting, so I did not teach.
