1″Be careful not to do your ‘acts of righteousness’ before men, to be seen by them. If you do, you will have no reward from your Father in heaven.
16″When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show men they are fasting. I tell you the truth, they have received their reward in full. 17But when you fast, put oil on your head and wash your face, 18so that it will not be obvious to men that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.
Matthew 6: 1, 16-18
Our Lord, fearing the abuse on our behalf of things He means for His glory, instructs us as to the motivations and manners through which we should fast.
Mosaic law prescribed one fast annually – the Day of Atonement. The Pharisees added two fasts weekly, Mondays and Thursdays, and used them as occasions for public displays of piety.
It wasn’t hard to spot one who was fasting; tradition held that an individual who was fasting would tear their clothing, wear sackcloth, and douse themselves with dust and ashes. Often, the mournful faster would allow their hair to become messy, and would refrain from bathing for a period.
The true function of fasting, however, was to indicate deep repentance and contrition, expressed through the temporary devoting of all one’s energies to prayer and spiritual communion. But fasting that requires a spectator is mere acting.
Jesus saw to eliminate such acting, and therefore prescribed that an individual should fast in an inward sense – refuse food and drink for the purposes of pursuing God all the more fully, all the while ensuring his outward appearance gave no indication of, “Behold! I love my God so much I am refusing to eat! I am the holiest of the holy that walk among us!”
Jesus desired to deal with the heart and not merely external appearances. For this reason He intended that outward signs of fasting were not enough, intending instead that the individual in the middle of a fast would forego the typical outwards signs of a fast. He wanted the heart, and for that reason the show of sorrow was not enough, but the change of heart.
Jesus didn’t intend for us to give up sweets for the 40 days before Easter.
He intended for us to give up any allegiance to any earthly thing, instead turning our affection, devotion, and reliance to Him and Him alone.
It makes me wonder: what other activities do I engage in on a daily basis from an external sense alone?
Do I truly love my wife with all my available thought and energy, or do I go through the motions?
Do I minister with a full outpouring of my being, or do I give lip service?
Do I pray from the most inward parts of my heart, or do I recite my top-10 list of wants?
Do I passionately pursue God with every ounce of my being, or do I do the “church thing” and leave it at that?
Christ seems to be using fasting as a microcosm for our entire walk: fast not in an outward appearance alone, but with everything you are; pursue His Glory through renouncing earthly restraints.
In the same way, live your entire life fully devoted to knowing Him and seeing His face; don’t be a surface Christian, but understand the implications His life inside of us has, understand life is 100% spiritual and its every facet is important to Him.
