I've been thinking lately about the need for academics to write clear prose. Instead of giving examples of those who do this poorly (!), I'll mention one who does this well: Doug Moo. I've been reading through his commentary on Philemon as part of my devotions. Virtually every sentence is crisp and clear instead of complicated and cumbersome.
So when I saw this clip by Marvin Olasky--in answer to the question of what we can learn from Calvin--I gave a hearty amen!
