Saints,

I highly recommend these audiobooks for anyone who preaches. It is a very good health check as they highlights the high calling and solemn responsibility of those proclaiming his word. Preacher, if you are not staggered and cut through your heart by these messages, may God have mercy on you. If you are about to become a preacher, you do well to learn from these old masters. All for free and read for you. May God richly bless those who narrated and recorded these messages.
