Come now, little man, turn aside for a while from your daily employment, escape for a moment from the tumult of your thoughts. Put aside your weighty cares, let your burdensome distractions wait, free yourself awhile for God, and rest awhile in Him. Enter the inner chamber of your soul, shut out everything except God and that which can help you in seeking Him, and when you have shut the door, seek Him. Now, my whole heart, say to God, 'I seek your Face, Lord, it is your Face I seek.' -- St. Anselm, Proslogion
“I have sought Thy Face. I have sought for Thee and none other beside Thee. Thy Face is my only reward. I will seek Thy Face, O Lord: in this demand will I persevere. Indeed I will not look for any unworthy object, but only Thy Face that I may love Thee more generously, because I find none other more precious. Thy Face is the reward of the elect. The righteous shall dwell under Thine eyes, and when they will love Thy Face, they will eat the bread of the sweat of their brow (Genisis:3:19):
“Let us return, wiping away the sweat, let us end the weariness and the weeping that we may shine in Thy all satisfying Face. Neither let us search any more, because there is nothing better. Let us not abandon Thee, and we shall not be abandoned by Thee. Because what was said about the Lord, after the Resurrection? I will be filled with overflowing joy with Thy Face, because without Thy Face, there would not be joy for us.”
— St. Augustine
