Fasting

Fasting in the Hebrew Scriptures is introduced as a solemn act of “afflicting the soul” and is linked to repentance and atonement. Leviticus 16:29 commands the people to “afflict your souls, and to do no work” on the Day of Atonement, establishing a corporate rhythm of self‑denial before God. The prophetic literature expands the purpose of fasting beyond ritual purity; Isaiah 58:6‑7 declares that the fast God chooses is “to loose the bonds of wickedness, to undo the heavy burdens… to feed the hungry and shelter the homeless,” thereby connecting the practice to justice and compassion.

The narrative of the Old Testament records several notable individual fasts that illustrate both personal devotion and communal crisis. Moses spent forty days and forty nights on Mount Sinai “neither ate bread nor drank water” (Exodus 34:28), a period of divine encounter that set a precedent for prolonged abstinence. In the post‑exilic period, Daniel “fasted and prayed” while seeking the Lord’s mercy for his people (Daniel 9:3), and Queen Esther called the Jews to “fast… for three days” before she approached the king (Esther 4:16), showing fasting as a preparatory prayer in moments of existential danger.

In the New Testament, Jesus models fasting as part of his preparation for ministry, stating that after his baptism he “fasted forty days and forty nights” in the wilderness (Matthew 4:2). His teaching in the Sermon on the Mount then reframes the outward appearance of fasting: “When you fast, anoint your head and wash your face, that your fasting may not be seen by others… but by your Father who is in secret” (Matthew 6:16‑18). This instruction emphasizes the interior motive of fasting—humility before God—over any public display.

The early Christian community continued the practice as a means of seeking divine guidance. In Antioch the believers “worshiped the Lord and fasted” before sending out Paul and Barnabas on missionary work (Acts 13:2‑3), and in Lystra “with prayer and fasting they committed them to the Lord” when appointing elders (Acts 14:23). These passages demonstrate that fasting was incorporated into the church’s discernment processes, linking it with prayer and communal decision‑making.

Apostolic teaching also situates fasting within the broader ethic of self‑denial and service. Paul notes that “in all things we show ourselves as servants of God… in fasting, in chastity, in patience, in love” (2 Corinthians 6:4‑5), presenting fasting as one of several spiritual disciplines that bear witness to the gospel. While some scholars debate whether New Testament fasting should be understood primarily as a corporate liturgical act or as an optional personal practice, the scriptural witness consistently portrays it as a humble posture before God that accompanies prayer, repentance, and acts of mercy.
