In the Sermon Prep Time thread, some posters indicated that their sermon prep time is on a kind of "descending scale" -- more for Sunday morning, less for Sunday night, least for Wednesday night. These questions are for those who use such a descending scale (not for a debate from those who don't). On what basis do you justify the descending scale? Are Sunday morning sermons more important? Are the people who attend on Sunday morning more needy? Are the Sunday morning sermons allotted more time wise? Other thoughts, comments?
