Regarding sermon prep, I had Haddon Robinson at DTS, and his course is basically contained in his book, “Biblical Preaching.” I don’t follow his method to a T, but I do generally follow it, with many shortcuts that are necessary for ministry survival. I begin just with the old observation, interpretation, application process that we learned in Bible study methods. I try to jot down any issues that need to be resolved, to figure out why the Lord included this passage in this context, etc. I try to determine what the subject of the passage is, and what it is saying about the subject (Robinson explains this process). If I can, I take an initial stab at a main idea.
