Not for the weak of heart...

"Coming out from behind the pulpit is not for the weak of heart. It takes more work, rather than less, to offer a careful, expository treatment of the Scriptures without reference to a sheaf of detailed notes. It requires the preacher take time to assimilate the message so that the sermon comes from somewhere deep within. Structures will have to be memorized. The material will have to be mastered. It will be hard to make all of this happen late on Saturday night. This, of course, is not a bad thing. Experienced preachers may actually be refreshed by the challenge."
