"As iron sharpens iron, so a man sharpens the countenance of his friend." (Proverbs 27:17)

Sometime food was required in difficult straits - not fasting (Acts 27:33-44). Therefore, fasting is not an exclusive (uniform) pattern. Plus, we have neither command nor guidance on how to carry it out, which further corroborates the point.Paul wrote:So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, which are a shadow of things to come, but the substance is of Christ. Let no one cheat you of your reward, taking delight in false humility and worship of angels, intruding into those things which he has not seen, vainly puffed up by his fleshly mind, and not holding fast to the Head, from whom all the body, nourished and knit together by joints and ligaments, grows with the increase that is from God.
Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations -- "Do not touch, do not taste, do not handle," which all concern things which perish with the using -- according to the commandments and doctrines of men? These things indeed have an appearance of wisdom in self-imposed religion, false humility, and neglect of the body, but are of no value against the indulgence of the flesh. (Colossians 2:16-23)
