This isn't a first person narrative sermon. Haddon wrote the book on those, but I can't find an example online of him doing it. He is an excellent narrative preacher, though. He didn't start out that way, but through the years his preaching has shifted in that direction. This is a marvelous biographical sermon on the person of Philemon. I love how he is able to make the ancient world come alive. What would you say is the secret to making that happen?
The introduction is about 3 minutes if you want to skip past that.
