As previously mentioned, overindulgence in food and drink can weigh down the stomach, cloud the mind, and diminish the will. Many of us have likely experienced these consequences of excess. Therefore, at times, it is essential to refrain from food and drink in order to bring the body into subjection to the spirit, especially during the battles against temptation and for a heightened awareness of one’s sins, self-examination, and repentance. Fasting can be complete or partial, and its duration can vary based on the individual's strength and the intensity of the temptation faced. Ultimately, fasting should be for the individual’s own spiritual triumph over a desire-driven body, rather than for the purpose of appearing pious.
In that era, the Pharisees were particularly conscious of their outward display of fasting. The Jewish customs often included regular washing and anointing with oil; such practices were necessary due to the heat of Palestine. Nonetheless, the Pharisees chose not to wash, unkempt their hair, avoided anointing themselves, donned tattered garments, and threw ashes on their heads to attract attention and mislead others with their peculiar appearances. Their fast was less about true fasting and more about the illusion of piety; the crowds they deceived would commend them for this facade, which satisfied the hypocrites, as this was their sole motivation.
However, Christ calls for a different approach to fasting from His disciples. He admonishes them not to appear sorrowful or gloomy while fasting, to maintain their usual appearance, and, in general, to avoid drawing attention to themselves. This fast is not for others to see, but for oneself, and ultimately directed toward the heavenly Father, who observes all actions in secret and knows one’s innermost thoughts. As He recognizes the sincere good deeds, prayers, and fasting performed privately, He will reward them openly.
It is important to clarify that Christ’s teachings do not prohibit the visible practice of good deeds and prayers, provided they are not done for the sake of human recognition. Likewise, fasting is not discouraged if it serves to bring the body into submission to the spirit for the purpose of enhancing prayer and repentance, rather than to gain the admiration of others.
The aim of human existence on this earth is to attain eternal joy in the Kingdom of Heaven. Therefore, individuals should focus on what guides them toward this divine objective: selfless love for both neighbors and adversaries, performing acts of kindness, self-reflection, repentance, fasting, and prayer. These are the true treasures necessary for entering the Kingdom, treasures that cannot be taken by thieves or destroyed by decay, unlike the temporal riches of this life that are susceptible to loss.
