16 Moreover, when you fast, do not be like the hypocrites, with a sad countenance. For they disfigure their faces that they may appear to men to be fasting. Assuredly, I say to you, they have their reward. 17 But you, when you fast, anoint your head and wash your face, 18 so that you do not appear to men to be fasting, but to your Father who is in the secret place; and your Father who sees in secret will reward you openly. (Matthew 6:16–18, NKJV)
Spiritual pretenders do not prosper. The law of Moses required fasting only on the Day of Atonement (Leviticus 23:27). The Jews also fasted at other memorable anniversaries (Zechariah 8:18-19). The temptation to show this deprivation of food in the devoted service to God was too great for some. They let everyone know when they were afflicting their souls with a fast. How we portray ourselves to others as we do the Lord’s work is the lesson we must take from this. Do we make sure others know how much we have “suffered” for the Lord? Or, do we simply do the work the Lord gives us to do, unassumingly and diligently? The Lord sees your service and He will not forget it (Hebrews 6:10). That’s all that really matters to the faithful citizen of the kingdom (not how many “likes” you get on social media).
