All this and much more can be said as to the necessity of prayer to the being, and culture of piety in the individual. But prayer has a larger sphere, a more obligated duty, a loftier inspiration. Prayer concerns God, whose purposes and plans are conditioned on prayer. His will and His glory are bound up in praying. The days of God's splendour and renown have always been the great days of prayer. God's great movements in this world have been conditioned on, continued and fashioned by prayer. God has put Himself in these great movements just as men have prayed. Present, prevailing, conspicuous and mastering prayer has always brought God to be present. The real and obvious test of a genuine work of God is the prevalence of the spirit of prayer. God's mightiest forces surcharge and impregnate a movement when prayer's mightiest forces are there.
