H.O. Old’s work is very good; you can see the weathered features of many painstaking, tedious, and diligent hours of study, thought, and prayer. This is no slip-shod work. Full of very rich and well documented historical insights, all presented in a manner that is very accessible to most readers.
The wisdom & insight here is very helpful. The main thrust is to show that preaching is worship, and has been a part of the worship of God’s people from the beginning. It is not isolated to the 1950s, but rather is a long-honored tradition, worthy of continuation until the end of time. And preaching has always been solidly founded upon God’s Word.
