Last Sunday, 7/24, I dealt with the lists of qualifications for leaders in 1 Timothy 3 & Titus 1. Obviously, it was an overview. You can listen to the message & get the accompanying note sheet at http://sermon.net/covingtonbiblechurch.
I just received an article by Steve Cornell in which he deals with one of the more contrversial qualifications, "the husband of one wife." http://thinkpoint.wordpress.com/2011/07/29/husband-of-one-wife/.
It is worth the read.
