To fast is to abstain from certain foods and/or drinks for a specific period of time. Christian fasting is primarily a tool by which we humble ourselves before God, by submitting the flesh’s will to the spirit’s will in reverence to God. Jesus demonstrated a classic example of this when he fasted for 40 days in the wilderness prior to facing the devil in temptation (Luke 4:1-2). The Bible’s many examples of fasts suggest that fasting was an important part of a person’s walk with God and ministry. The Apostle Paul mentioned he fasted often during his ministry (2 Corinthians 11:27).

Purposes and examples of fasts in the Bible

Breakthroughs for Guidance:

  • Strategic breakthroughs and specific direction from the Holy Spirit (Acts 13:2-3; Acts 9:1-19)
  • Ezra proclaims fast to humble themselves, seek guidance and protection (Ezra 8:21); God answers their prayers in Ezra 8:23.

Confession and repentance:

  • Daniel fasts and prays, confessing sin and asking mercy from God, forgiveness for Israel’s sins and restoration of Jerusalem. His prayers are answered and Gabriel comes to give Daniel wisdom (Daniel 9)

  • People of Ninevah fast in repentance to avert the prophesied destruction (Jonah 3:5-10). God relents.

  • Certain demons only can be routed through prayer and fasting (Matthew 17:21)

Types of Fasts

How to Fast:

  • Identify the purpose, type and duration of the fast
  • Combine it with prayer: widow serving God in the temple (Luke 2:37); Cornelius (Acts 10:30); Elders sent out (Acts 14:22-24); Saul and Barnabas sent out (Acts 13:3)
  • Pray as a “spiritual sacrifice” during the times you would normally eat
  • Refrain from sex during fast: “Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer” (1 Corinthians 7:5 NKJV)
  • Forego comfort: Ahab tore clothes and wore sackcloth (1 Kings 21:27 NKJV); Ezra tore garment and plucked out hair; prayed on his knees w/hands spread out in confession (Ezra 9:3-15); Nehemiah wore sackcloth and put ashes on head (Nehemiah 9:1)
  • Express appropriate actions of feeling: Ezra prayed on his knees w/hands spread out to God in confession (Ezra 9:3-15); Nehemiah wept and mourned in prayer (Nehemiah 1:4); Mordecai wept, wailed and lay in sackcloth and ashes (Esther 4:1-2); David wept his son (2 Samuel 12:16-22)
  • Do it sincerely, not pretentiously: Joel said to weep, mourn and rend your heart, not your garment (Joel 2:12-13); Don’t fast in duplicity – modern example: fasting to seek guidance and to lose weight
  • Fast to be seen by God; not openly for man’s approval (Mathew 6:16,18); not as a means to earn religious honor or respect among people (Luke 18:9-14); anoint your head and wash your face (Matthew 6:17), so that people don’t realize you are fasting
  • In obedience: The purpose for a fast will be nullified by the continuation of sinful habits. God instructed the people, “Execute true justice, show mercy and compassion everyone to his brother. Do not oppress the widow or the fatherless, the alien or the poor. Let none of you plan evil in his heart against his brother” (Zechariah 7:9-10 NKJV); cease oppression of poor and observe the Sabbath with pure and joyful worship, not pleasure seeking (Isaiah 58:6-14).
