Matthew 6:16's lesson on fasting's purpose?
What does Matthew 6:16 teach about the true purpose of fasting?

Text of Matthew 6:16

“When you fast, do not be somber like the hypocrites, for they disfigure their faces to show men they are fasting. Truly I tell you, they already have their reward.”


Literary Context within the Sermon on the Mount

Matthew 6:1-18 addresses three core acts of piety—almsgiving, prayer, and fasting—each beginning with the warning “Beware of practicing your righteousness before men to be seen by them” (6:1). Fasting is placed third, linking bodily self-denial to the same God-centered motivation that must govern giving and praying.


Historical and Jewish Background of Fasting

Under the Mosaic Law only the Day of Atonement required national fasting (Leviticus 16:29). Post-exilic Judaism added voluntary fasts (Zechariah 8:19) and communal fasts during crises (Esther 4:16). By the first century, Pharisaic practice included twice-weekly fasts (Luke 18:12). Jesus addresses a culture where public display of asceticism had become a badge of honor.


Jesus’ Contrast with Hypocritical Practice

“Hypocrites” (Greek hypokritai) describes actors wearing masks. By intentionally disfiguring their faces—funeral-type whitened appearance, torn garments, ashes-on-head—such fasters sought social applause. Jesus warns that external theatrics nullify eternal reward; the only “paycheck” received is fleeting human admiration.


The True Purpose of Fasting: Godward Orientation

1. Humble Dependence: Fasting dramatizes Psalm 63:1, “My soul thirsts for You.” It is relational, not ritual.

2. Intensified Prayer: Acts 13:2-3 couples fasting with listening for God’s guidance; withholding food tunes the heart to the Spirit’s voice.

3. Repentance and Renewal: Joel 2:12—“Return to Me with fasting, weeping, and mourning”—shows that true fasting is a turning of the heart, not a hollow hunger strike.

4. Anticipation of the Bridegroom: Jesus implies His followers will fast in His bodily absence (Matthew 9:15) as an expression of longing for consummated fellowship.


Fasting and Reward: Heavenly vs. Earthly Recognition

Jesus repeatedly sets two treasuries in opposition (6:4,6,18):

• Earthly—applause, reputation, social capital.

• Heavenly—divine approval and spiritual intimacy.

The reward imagery echoes Isaiah 58:8-9, where genuine fasting brings light, healing, and answered prayer.


Practical Implications for Believers Today

• Secrecy: Anointing the head and washing the face (6:17) were daily hygiene. Normal appearance guards against performative spirituality.

• Motive Audit: Ask, “Would I fast if no one ever found out?”

• Balance: Biblical fasting abstains from food, not water, unless short-term; health considerations matter (1 Corinthians 6:19-20).

• Variety: Total, partial, or Daniel-type fasts (Daniel 10:3) may suit circumstance.

• Purpose Statement: Link each fast to a specific God-centered goal—repentance, direction, intercession, empathy for the poor.

Early Church Application and Testimony

The Didache 8:1 (c. AD 50-70) commands, “Fast…not with the hypocrites; they fast on Mondays and Thursdays, but you on Wednesdays and Fridays.” This directly echoes Matthew 6:16’s polemic against ostentation while affirming continued fasting practice. Eusebius documents pre-Nicean communal fasts before baptisms and Easter, showing the church maintained Christ-centered motives.


Psychological and Spiritual Benefits Confirmed by Modern Studies

Clinical research (e.g., intermittent-fasting neurology studies, 2019 Cell Metabolism) reveals heightened neuroplasticity and clarity during caloric restriction, underscoring a Creator-designed body that turns physical weakness into cognitive and emotional attentiveness—conducive to prayer and reflection. These findings align with Romans 12:1’s call to present the body as a living sacrifice.


Common Misconceptions Addressed

• “Fasting earns merit.” Scripture presents it as a grace-response, not a leverage mechanism (Ephesians 2:8-9).

• “Public fasts are forbidden.” Corporate fasts (Acts 14:23) are valid when God-focused, not self-advertising.

• “Only food counts.” While the Bible’s paradigm is dietary, temporarily relinquishing lawful pleasures (1 Corinthians 7:5) can apply the principle when food abstention is impossible.


Conclusion

Matthew 6:16 teaches that the essence of fasting is God-directed humility, not human-directed display. Real fasting turns physical appetite into spiritual appetite, pursuing the Father’s reward—intimacy with Him—while disregarding the spotlight of men.

How can we ensure our fasting aligns with God's desires, not human praise?
