Atheist, Peter Atkins, was in fine form in the latest episode of Unbelievable (Has Science Explained Away God?). No. Seriously. Continual face palm. I haven't seen this level of obtuse blindness in quite some time. For that reason alone, I would direct listeners to the discussion. Just think of the term enmity.
James White shared a good word last week on the subject of majoring on the majors and minoring on the minors in the church. A good reminder.
While Brian Rosner doesn't come at the question of the Law from a distinctly (classically, one might say) Reformed perspective, his lectures are thought-provoking and scholarly. The advanced listener who enjoys the subject of Paul and the Law will want to give it a go.
