Some time ago I posted a link to the interview we had with Dr. Joseph A. Pipa, on Christ the Center, regarding the preaching of William Perkins. You can listen to it here. Dr. Pipa wrote his doctoral dissertation on the preaching of Perkins. He recently gave a lecture on the life of Perkins at the 2010 Whiteabbey Congregational Church Puritan Conference. You can listen to the lecture here. You can hear the rest of Dr. Pipa's lectures from that conference here.
