Prayer and converse with God is a supreme good: it is a partnership and union with God. As the eyes of the body are enlightened when they see light, so our spirit, when it is intent on God, is illumined by his infinite light. [From a homily by Saint John Chrysostom.]
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. [From the treatise On Spiritual Perfection by Diadochus of Photice]
The time for promises was in the time of the prophets, until John the Baptist; from John until the end is the time of fulfillment. God, who is faithful, put himself in our debt, not by receiving anything but by promising so much.
