“He is truly great that is great in charity. He is truly great that is little in himself, and maketh no account of any height of honor. And he is truly learned that doeth the will of God, and forsaketh his own will.”

Context: He who is satisfied has never truly craved, and he who craves for the light of God neglects his ease for ardor, his life for love, knowing that contentment is the shadow not the light. The great yearning that sweeps eternity is a yearning to praise, a yearning to serve. And when the waves of that yearning swell in our souls all the barriers are pushed aside: the crust of callousness, the hysteria of vanity, the orgies of arrogance. For it is not the I that trembles alone, it is not a stir out of my soul but an eternal flutter that sweeps us all. No code, no law, even the law of God, can set a pattern for all of our living. It is not enough to have the right ideas. For the will, not reason, has the executive power in the realm of living. The will is stronger than reason and does not blindly submit to the dictates of rational principles. Reason may force the mind to accept intellectually its conclusions. Yet what is the power that will make me love to do what I ought to do?
