At Dallas Theological Seminary there is a godly well-loved professor who has taught more than 50 years. Just recently I've been reading a copy of his book, Teaching To Change Lives. It was published in 1989. Here is a video (that needs to be on YouTube!) I found @ the Dallas Seminary website.

During our college years, my future husband asked our Sunday School teacher if they knew Howard Hendricks. "He replied, Howard Hendricks!, we majored in Howard Hendricks." As far as I can tell, he is still teaching at the seminary and its been over 50 years. I say this in reverence to the Lord Almighty, to Him be all honor for the service of this servant of His.
