Quiet Talks on Prayer 

You see sin is slapping God in the face. It may be polished, cultured sin. Sin seems capable of taking quite a high polish. Or it may be the common gutter stuff. A man is not concerned about the grain of a club that strikes him a blow. How can He and I talk together if I have done that, and stick to it-not even apologized. -from "Why the Results Fail" What is prayer? Can humans influence God’s will? Why does it seem that many prayers go unanswered? The mysteries of the communication between God and his faithful are explored in this 1904 guide to the power and puzzle of prayer: how God heeds our entreaties, the ideal spirit with which to pray, and even what prayer means in the grand scheme of The Universe. Those who pray will find this a source of comfort and enlightenment even today, a century after it was first published.
