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).
After elaborating on prayer’s motive, method, and manner in Matthew 6:5-15, Jesus returns to the motives of personal piety in today’s passage. Fasting often accompanied prayer. Like prayer, hypocrites used fasting as their chance to be praised by others for their voluntary deprivation and affliction of the soul. While not commanded under the new covenant, fasting was (is) a period of intense spiritual devotion. It was associated with recognizing one’s sin with godly sorrow and repentance (Nineveh, Jonah 3:5-10; Luke 11:32; Saul, Acts 9:9-11). The broader principle Jesus taught applies to every action of self-sacrifice. Instead of bragging and displaying religious practices to be praised by others, we aim to please the eyes of our heavenly Father. The reward of human praise momentarily feeds pride and fades quickly. But attentive, faithful service to the Lord will be evident and eternally rewarded. When we love the praise of men more than the praise of God, we confess ourselves, not Christ (John 12:42-43). So, go about your daily service to the Lord without regard for whether others see you. The Father sees you, and that is enough.
