It is not necessary for a preacher to express all his thoughts in one sermon. A preacher should have three principles: first, to make a good beginning, and not spend time with many words before coming to the point; secondly, to say that which belongs to the subject in chief, and avoid strange and foreign thoughts; thirdly, to stop at the proper time.
Martin Lutherwhat the situation will be like in the world before the Lord returns, namely, Christ will be despised, and the preachers of the Gospel will be regarded as fools.
