Devotion according to J.C. Ryle

DEVOTION is neither private nor public prayer; but prayers, whether private or public, are particular parts or instances of devotion. Devotion signifies a life given, or devoted, to God. He, therefore, is the devout man, who lives no longer to his own will, or the way and spirit of the world, but to the sole will of God, who considers God in everything, who serves God in everything, who makes all the parts of his common life parts of piety, by doing everything in the Name of God, and under such rules as are conformable to His glory. We readily acknowledge, that God alone is to be the rule and measure of our prayers; that in them we are to look wholly unto Him, and act wholly for Him; that we are only to pray in such a manner, for such things, and such ends, as are suitable to His glory.
