In Bible study and sermon or class preparation, many little things come into play that are part of my routine. After 50 years of ministry, I have pretty well defined my comfort zone for my work. This includes a certain table I like to use, which Bible I work from, and even what kind of pen and notepad I use for making my notes.
Yes, I am one of those old-fashioned guys that still takes all his sermon notes on a lined notepad. I may or may not enter the notes into the computer later, but it will always be the handwritten copy which goes with me into the pulpit.
