Fasting as Spiritual Warfare
Fasting humbles the body and sharpens prayer — Jesus said some battles go out only by prayer and fasting.
After the disciples failed to cast out a demon, Jesus said, 'this kind goeth not out but by prayer and fasting' (Matthew 17:21). Fasting is not a hunger strike to twist God's arm — it is voluntary self-denial that focuses the soul, humbles the flesh, and intensifies prayer. From Moses to Anna to the early church, fasting accompanies breakthrough.
What Scripture Teaches
- 1Jesus assumed His followers would fast (Matthew 6:16, 'when ye fast')
- 2Some spiritual battles require prayer and fasting (Matthew 17:21, Mark 9:29)
- 3Fasting was central to seeking God in crises (Ezra 8:21-23, Esther 4:16)
- 4The early church fasted before major decisions (Acts 13:2-3, 14:23)
- 5Fasting is to be done unto God, not to be seen (Matthew 6:17-18)
- 6It is humbling the soul, not earning favor (Psalm 35:13)
Key KJV Scriptures
"Howbeit this kind goeth not out but by prayer and fasting."
"But thou, when thou fastest, anoint thine head, and wash thy face; That thou appear not unto men to fast, but unto thy Father which is in secret..."
"Therefore also now, saith the LORD, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning:"
"As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them."
Why It Matters
Fasting puts the body under the spirit. It clears the static and bends the soul toward God. Where prayer alone has gone unanswered, prayer with fasting often breaks through.
Application for Today
Start with one meal. Drink water. Use the time you would have eaten to pray Scripture and intercede. Don't broadcast it. Let your Father in secret reward you openly.

Frequently Asked Questions
Do I have to fast as a Christian?
Scripture commands fasting in spirit and assumes it in practice (Matthew 6:16-18). It is not a salvation issue, but it is a normal Christian discipline.
What if I have a medical reason I can't fast from food?
Fast from something else meaningful — entertainment, social media, comforts — and devote that time to prayer. The principle is voluntary denial for God's sake.
