"My Pastor preaches too long." This is a complaint often heard from those who sit in the pew. It is interesting that this seems to be an issue. Having read not a few sermons from the Puritans, I get the idea that time constraints were meaningless to them. But, we live in a different world.

Likewise, there are others who preach for a hour and one wonders where the time has gone.
