Weapon of Prayer [EPUB ebook] 

It must never be forgotten that Almighty God rules this world. He is not an absentee God. His hand is ever on the throttle of human affairs. He is everywhere present in the concerns of time. "His eyes behold, his eyelids try the children of men." He rules the world just as He rules the Church by prayer. This lesson needs to be emphasized, iterated and reiterated in the ears of men of modern times and brought to bear with cumulative force on the consciences of this generation whose eyes have no vision for the eternal things, whose ears are deaf toward God.
