Haddon was my preaching professor when I was a student at Gordon-Conwell, and he was instrumental in opening my eyes to the "big idea" of preaching. I have never considered myself as a preacher, but Haddon's book (Biblical Preaching) and teaching have helped me tremendously. He has sharpened my homiletical skills, encouraged me to explore creative ideas in preaching, and challenged me to be a preacher that is faithful to the Bible.
More important for me is knowing the man himself. His deep love for the Scripture and concern for students (I recalled a number of times he asked me how I was coping in seminary) had been exemplary. When I was a student, we celebrated Haddon's 50th anniversary in ministry. I wondered back then what made a man remain so faithful in his service for the Lord and the church. I remembered clearly that the service inspired me to remain faithful to my calling.
Haddon, you will be deeply missed. I thank you for your life, ministry, and the legacy you have left behind in influencing many preachers today.
