What Were Bavinck's Lectures Like?
His classes met in the morning. Before he began his lecture, usually at 9 a.m., he stood near the stove and we gathered around him and asked him questions. We touched upon all kinds of subjects--an article by Dr. Kuyper, a novel that appeared recently in one of the modern languages, socialism, psychology--anything. And when he answered us he proved to be well informed, and usually he placed the subject in the light of the great principles of the Word of God. Then we were treated to a brief improvisation and learned much. After that, glancing at his watch, he would say, 'Gentlemen, it is time to begin.' Then he led us in prayer, and lectured dogmatics.--account given by Idzerd Van Dellen in his In God's Crucible: An Autobiography (Baker 1950), 42-43; quoted in Eric Bristley, Guide to the Writings of Herman Bavinck (Reformation Heritage 2008), 14
He spoke in such a way that we often forgot to take notes as we were supposed to do . . . and just listened to his enthusiastic presentation of the subject.
I love that last sentence.
