Here is another book on prayer by E.M. Bounds called, 
Essentials Of Prayer in which he writes.
“The present day church has vast machinery. Her activities are great, and her material prosperity is unparalleled. The name of religion is widely spread and well-known. Much money comes into the Lord’s treasury and is paid out. But here is the question: does the work of holiness keep pace with all this?
Are our preachers thirsting after righteousness, desiring the sincere milk of the Word, that they may grow thereby? Are they really seeking to be holy men? Of course men of intelligence are greatly needed in the pulpit, but prior to that, and primary to it, is the fact that we need holy men to stand before dying men and proclaim the salvation of God.”
Searching questions raised here. Another gem of an exerpt.
