Covenant Seminary has reworked the Ministry Resources component of their website and now lists recommended messages dealing with cultural, emotional, relational, spiritual, and theological challenges in life. You can still search the whole database if you prefer; dozens of messages have been added in the last few months.
Speakers include Bryan Chapell, Zack Eswine, John Piper, Tim Keller, J. I. Packer, and Jerram Barrs.
The seminary also offers 21 classes from their M.A.T.S. (Master of Arts, Theological Studies - an MDiv without the languages, preaching, and counseling, intended for lay ministry leaders) totally FREE. This is another recent venture called Covenant Worldwide.
