Authority and Preaching

If you lose confidence in the Bible’s authority, does that have any effect on preaching? The words of D. Martyn Lloyd-Jones written 40 years ago remain relevant today:

“If you have not got authority, you cannot speak well, you cannot preach…But as belief in the great doctrines of the Bible began to go out, and sermons were replaced by ethical addresses and homilies, and moral uplift and socio-political talk, it is not surprising that preaching declined. I suggest that that is the first and the greatest cause of this decline.” (20-21)
