Four very reliable and sound, biblical voices.
Tremendous biblical and theological answers.
I usually do not post videos that are lengthy, but this plenary discussion featuring Don Carson, Tim Keller, Kevin DeYoung, and John Piper from The Gospel Coalition 2013 National Conference is very rich and worth watching in its entirety. Many subtopics are approached and addressed and I think you will benefit from watching this discussion. This discussion is fast-paced, enjoyable, practical, yet all the while, deep and compelling.
