Dr. Douglas Moo’s exegetical commentary on the book of Romans is considered by many to be the best Romans commentary in print. So it’s exciting that BiblicalTraining.org has made available a free set of lectures and class discussions by Dr. Moo on Romans. You can stream the video online, or download the audio, for free. (You need to create an account to download the audio.)
You might consider giving to BiblicalTraining.org so that they can continue to make such amazing resources available at no cost.
