“Be glad then that you are overwhelmed, and do not be saddened because he has overcome you. A thirsty man is happy when he is drinking, and he is not depressed because he cannot exhaust the spring. So let this spring satisfy your thirst, and not your thirst the spring…Be thankful then for what you have received and do not be saddened at all that such an abundance still remains.”
— St. Ephrem the Syrian, deacon
