The mind is fixed on God…

There are three kinds of attention that can be brought to vocal prayer: one which attends to the words, lest we say them wrong; another which attends to the sense of the words; and a third which attends to the end of the prayer, namely, God, and to the thing we are praying for. This last kind of attention is most necessary, and even uneducated people are capable of it. Moreover, this attention, whereby the mind is fixed on God, is sometimes so strong that the mind forgets everything else.
–Saint Thomas Aquinas (1225-1274)

Give yourselves to God who…

Do not think that you will be set free by things which are harmful. You do not know what is good for you in the way that God does. Therefore, give yourselves to him who holds the key to the universe. For even if you ask nothing but merely groan under the impulse of the grace that dwells in you, he handles your affairs wisely and will ensure that you get what you need.
–Saint Theodoret of Cyrus (c. 393-457)

Brazenly asking God…

If we go on crying out and do not receive any answer, this is for our advantage: instead of losing heart and growing weary, we should go on brazenly asking God, for it is certain that “at an acceptable time” and at the appropriate hour he will answer us and deliver us.
–Sahdona (b. 600-649)
