Since the angels and souls are incorporeal beings, they are not in a particular place, yet neither are they everywhere. They do not sustain all things, but themselves depend on Him Who sustains them. Hence they, too, are in Him Who sustains and embraces all things, and they are appropriately delimited by Him. The soul, since it sustains the body with which it is created, is everywhere in the body, although not in the sense of being located in a place or encompassed; but it itself sustains, encompasses and quickens the body, by virtue of the fact that it is in God's image.
I consider those fallen mourners more blessed than those who have not fallen and are not mourning over themselves; because as a result of their fall, they have risen by a sure resurrection.
To act 'according to one’s strength' means to use a little less than necessary both of food, and drink, and sleep... As for food, restrain yourself when you wish to eat a little more, and in this way you will always make use of it moderately.
If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
Those who live in obedience are strangers to love of money. For where even the body has been given up, what is left to be one's own? Only in one way can they be harmed, namely by being ready and quick to go from place to place. I have seen material possessions make monks patient to remain in one place. But I praise those who are pilgrims for the Lord.
A human being who does not endure courageously the unpleasant burdens of temptations, will never produce fruit worthy of the divine wine-press and eternal harvest, not even if one possesses all other virtues. For one is only perfected through zealously enduring both all the voluntary and involuntary afflictions.
Let no one think, my brother-Christians, that it is the duty only of priests and monks to pray without ceasing, and not of laymen. No, no; it is the duty of all of us Christians to remain always in prayer. For look what the most holy Patriarch of Constantinople, Philotheus, writes in his life of St. Gregory of Thessalonica. This saint had a beloved friend by the name of Job, a very simple but most virtuous man. Once, while conversing with him, His Eminence said of prayer that every Christian in general should strive to pray always, and to pray without ceasing, as Apostle Paul commands all Christians, 'Pray without ceasing' (I Thessalonians 5:17), and as the prophet David says of himself, although he was a king and had to concern himself with his whole kingdom: 'I foresaw the Lord always before my face' (Psalms 15:8), that is, in my prayer I always mentally see the Lord before me. Gregory the Theologian also teaches all Christians to say God’s name in prayer more often than to breathe. So, my Christian brethren, I too implore you, together also with St. Chrysostom, for the sake of saving your souls, do not neglect the practice of this prayer. Imitate those I have mentioned and follow in their footsteps as far as you can.
If we prefer not to empty out all we possess for the love of God, let us at least not callously hold on to everything ourselves. Let us do something, then humble ourselves before God and obtain forgiveness from Him for what we have failed to do. For His love for mankind makes up for our omissions...
