From The Gospel Coalition: an interview with Dr. George Guthrie on teaching 2 Corinthians
Here is an interview by Nancy Guthrie where she talks with Dr. George Guthrie about how to teach 2 Corinthians. Dr. Guthrie is Professor of Bible at Union University in Jackson, Tennessee. According to the notes for the interview,
Guthrie provides clarity on the “triumphal procession,” our transformation “from one degree of glory to another,” as well as how to teach on financial giving in a way that captures the beauty of the passage. Guthrie has participated in numerous Bible translation projects and wrote Read the Bible for Life: Your Guide to Understanding and Living God’s Word as well as the volume on 2 Corinthians in the Baker Exegetical Commentary on the New Testament series.
I think this could be quite helpful for anyone seeking to teach 2 Corinthians.
