Edward M. Bounds 
Power Through Prayer [EPUB ebook] 

Power Through Prayer is one of EM Bounds many classic works on prayer. He is practical yet spiritual, challenging us to seek God in passionate and unrelenting prayer.Christ did not come for the righteous but for the sinner and He calls us to pray like he did to the Father in a continual basis. Bounds in this work outlines what kind of heaven and earth shattering effects prayer can have from the individual person to the very ministry that someone may be trying to perform. There is no limit or bounds to what kind of power to faith prayer can have.
