Perfection consists in one thing alone, which is doing the will of God. For, according to Our Lord's words, it suffices for perfection to deny self, to take up the cross and to follow Him. Now who denies himself and takes up his cross and follows Christ better than he who seeks not to do his own will, but always that of God? Behold, now, how little is needed to become as Saint? Nothing more than to acquire the habit of willing, on every occasion, what God wills.
