Purpose in Prayer - Edward M Bounds - Bog

The more praying there is in the world the better the world will be, the mightier the forces against evil everywhere. Prayer, in one phase of its operation, is a disinfectant and a preventive. It purifies the air; it destroys the contagion of evil. Prayer is no fitful, shortlived thing. It is no voice crying unheard and unheeded in the silence. It is a voice which goes into God's ear, and it lives as long as God's ear is open to holy pleas, as long as God's heart is alive to holy things.
