Commentary: "Fasting, or occasional abstinence from food, in order to bring the body into subjection to the spirit, is a practice frequently mentioned in the Bible, and generally in connection with prayer. David fasted, when his child was sick. Daniel fasted, when he sought special light from God. Paul and Barnabas fasted, when they appointed elders. Esther fasted, before going in to Ahasuerus. It is a subject about which we find no direct command it the New Testament. It seems to be left to every one's discretion, whether he will fast or not. There is great wisdom in this. Many a poor man never has enough to eat, and it would be an insult to tell him to fast. Many a sickly person can hardly be kept well with the closest attention to diet, and could not fast without bringing on illness. It is a matter in which every one must be persuaded in his own mind, and not be hasty to condemn others, who do not agree with him. One thing only must never be forgotten. Those who fast should do it quietly, secretly, and without ostentation. Let them not "appear to men" to fast. Let them not fast to man, but to God." - JC Ryle
