“When you undertake to begin any task whatever,” a certain elder advises, “conscientiously ask yourself this question: ‘If I were visited by the Lord at his moment, what would I do?’ Take care to listen well to what your conscience answers you. If it reproves you, immediately forsake what you had decided to do and begin some other task of which it approves and which, so as assuredly to complete it, is intrinsically rewarding. The virtuous worker must at every moment be ready to face death.
“When you fall into your bed to sleep, or get up from sleep, when you eat or work, when you are thinking or your mind is idle, constantly say to yourself: ‘If the Lord were to call me at this moment, would I be ready?’ Listen also with care to what your conscience tells you and do not fail to comply with its directions. Your heart will, indeed, assure you that God has had mercy on you.” ~ The Desert Fathers
