This is the first time such a book has been seriously attempted. It is intended to provide a clear, constructive understanding and perhaps teachings of religious revival. Frederick Morgan Davenport delves into man's mind, from primitive time to the new evangelism. He captures the reasons, psychological and sociological, that commits man to religious experiences, likening it to politics in the sense that public gathering has always taken place and will continue. For this reason the helpfulness and inspiration of man will cause him to seek spiritual meaning in life. This is precisely Davenport's motive - to contribute to the better ordering of religious method - that the tide may be rationally guided into reservoirs, channels and ditches to irrigate a thirsty land and not overwhelm it, but eliminate its destructive trails.
