Here is an outstanding series of lectures that Edward Donnelly gave at the 2001 Trinity Baptist Pastors Conference. The subject was “Helps for Today’s Pastors: Case Studies in the Life of Paul.” They are well worth the time it takes to listen to them.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
