Abba Seraphim's lectures
As one who has been listening to Abba Seraphim's lectures for the last month (and will, alas, miss the final one in this series) I can only echo what you say. He brings a lightness of touch and a gentle humour that keeps one interested and makes the experience a memorable one.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:10)
