Dr. Erik Thoennes (who I t.a. for at Biola) and Dr. David Talley are the primary teaching pastors at Grace Evangelical Free Church in La Mirada, CA, where they semi-recently began preaching through Romans.
I do not attend Grace EV Free, but I listen to sermons from there all the time. Talley and Thoennes are two of the best preachers I know, and not only has my girlfriend (who does go to the church and is dang smart) attested to how good this series has been, but I've begun listening through it and have been both convicted and blessed.
It's the series called "The Story of Redemption" when you click on the link. Enjoy.
