But I have also been present when an appeal of a much more emotional and also more 'pneumatic' kind has worked wonders on a modern audience. Where God gives the gift, the 'foolishness of preaching' is still mighty.--C. S. Lewis, 'Modern Man and His Categories of Thought,' in Present Concerns (London: Fount, 1986), 66
But best of all is a team of two: one to deliver the preliminary intellectual barrage, and the other to follow up with a direct attack on the heart.
