Last week, Fr. Stephen Freeman posted an excellent Lenten reflection: Why We Fast. Here is an excerpt:
And it is the same path of inner knowledge of God (with all its components) that is the proper context of fasting. If we fast but do not forgive our enemies – our fasting is of no use. If we fast and do not find it drawing us into humility – our fasting is of no use. If our fasting does not make us yet more keenly aware of the fact that we are sinful before all and responsible to all then it is of no benefit. If our fasting does not unite us with the life of God – which is meek and lowly – then it is again of no benefit.
Fasting is not dieting. Fasting is not about keeping a Christian kosher. Fasting is about hunger and humility (which is increased as we allow ourselves to become weak). Fasting is about allowing our heart to break.
I have seen greater good accomplished in souls through their failure in the fasting season than in the souls of those who “fasted well.” Publicans enter the kingdom of God before Pharisees pretty much every time.
Why do we fast? Perhaps the more germane question is “why do we eat?” Christ quoted Scripture to the evil one and said, “Man does not live by bread alone but by every word that proceeds from the mouth of God.” We eat as though our life depended on it and it does not. We fast because our life depends on the word of God.
