Do not be surprised that you fall every day; do not give up, but stand your ground courageously. And assuredly, the angel who guards you will honour your patience. While a wound is still fresh and warm, it is easy to heal…

St. John Climacus

They tell the story that on one occasion, while the blessed Anthony [St. Anthony the Great] was dwelling in the desert, thoughts of dejection and despair rose up in his mind, and he was in deep gloom of thought, and said to God, "Lord, I wish to live, but my thoughts will not permit me to do so. What will I do in my tribulations to be saved?" And he came a little nearer [to the town] from the place where he was, and he saw a man who was like to himself, and was in his own form, and he was sitting down and twisting palm leaves into ropes ; and this man rose up from his work, and prayed, and afterwards he sat down again and continued his work, and then he stood up once more, and prayed. Now the man was an angel who had been sent from God to correct and to admonish the blessed Anthony, who afterwards heard him say to him, "O Anthony, do you also do this and live"; and when Anthony heard this, the blessed man had great joy, and afterwards he did as the angel had done, and lived.

from Sayings of the Holy Desert Fathers

While the dying person addresses his last words to us, suddenly his tongue is at a loss, his eyes dim, his mouth falls silent, his voice paralyzed when the Lord’s troops have arrived, when His frightening armies overwhelm him, when the divine bailiffs invite the soul to be gone from the body, when the inexorable lays hold of us to drag us to the tribunal… Then the angels take the soul and go off through the air. There stand principalities, powers and leaders of the adverse troops who govern the world, merciless accusers, strict agents of an implacable tax bureau, like so many examiners that await the soul in the air, ready to demand a reckoning, to examine everything, brandishing their claims, that is to say our sins: those of youth and of old age, those intentional and those not so, those committed by actions and those by words or thoughts. Great then is the fear of the poor soul, inexpressible its anguish when it sees itself at grips with these myriads of enemies, who stop it, push and shove it, accuse it, hinder it from dwelling in the light, from entering into the land of the living. But the holy angels, taking the soul, lead it away.
