The following is from today's Office of Readings:
Anyone who loves God in the depths of his heart has already been loved by God. In fact, the measure of a man’s love for God depends upon how deeply aware he is of God’s love for him.
No one who is in love with himself is capable of loving God. The man who loves God is the one who mortifies his self-love for the sake of the immeasurable blessings of divine love. Such a man never seeks his own glory but only the glory of God. If a person loves himself he seeks his own glory, but the man who loves God loves the glory of his Creator. Anyone alive to the love of God can be recognized from the way he constantly strives to glorify him by fulfilling all his commandments and by delighting in his own abasement. Because of his great majesty it is fitting that God should receive glory, but if he hopes to win God’s favor it becomes man to be humble. If we possess this love for God, we too will rejoice in his glory as Saint John the Baptist did, and we shall never stop repeating: His fame must increase, but mine must diminish.
As the Apostle says: If we are taken out of ourselves it is for the love of God; if we are brought back to our senses it is for your sake. (From the treatise On Spiritual Perfection by Diadochus of Photice, bishop, Cap. 12. 13. 14: PG 65, 1171-1172)
