Prayer and virtues…

Perseverance in prayer cleanses the intellect, illumines it, and fills it with the light of truth. The virtues, led by compassion, give the intellect peace and light. The cleansing of the intellect is not a dialectical, discursive and theoretical activity, but an act of grace through experience and is ethical in every respect. The intellect is purified by fasting, vigils, silence, prayer, and other ascetic practices.
–Saint Isaac of Syria (Seventh Century)

In God’s presence…

The following consideration should never be forgotten when we go to prayer, namely, that we draw near to God and place ourselves in His presence principally for two reasons. The first is to render to God the honor and the homage we owe Him, and this can be done without God speaking to us or we to Him, for the duty is fulfilled by acknowledging that He is our Creator. . . . The second reason is to speak to God and to listen to Him when He speaks to us by His inspirations and the interior movements of grace. One or other of these two advantages can never fail to be derived from prayer.
–Saint Francis de Sales (1567-1622)

Speak to our Lord…

If, then, we can speak to our Lord, let us do so in praise and supplication: if we are unable to speak, let us remain in his presence notwithstanding, offering him our silent homage; he will see us there, our patience will touch him and our silence will plead with him and win his favor. Another time, to our utter astonishment, he will take us by the hand, and converse with us, and make a hundred turns with us in his garden of prayer. And even should he never do this, still let us be content to know it is our duty to be in his retinue, and that it is a great favor and a greater honor for us that he suffers us in his presence.
–Saint Francis de Sales (1567-1622)

Nature and grace…

God displays in a marvelous manner the incomprehensible riches of his power in the vast array of things that we see in nature, but he causes the infinite treasures of his goodness to show forth in an even more magnificent way in the unparalleled variety that we see in grace. In a holy excess of mercy, God is not content in solely with granting to his people, that is, to the human race, a general or universal redemption whereby everyone can be saved. God has diversified redemption in many ways, so that while God’s generosity shines forth in all this variety, the variety itself, in turn, adds beauty to his generosity.
–Saint Francis de Sales (1567-1622)
