Role of prayer fasting in spiritual trials?
What role do prayer and fasting play in overcoming spiritual challenges today?

Context: A Real Battle, A Real Solution

Matthew 17 records a boy tormented by a demon. The disciples’ normal methods failed, but Jesus said, “But this kind does not go out except by prayer and fasting.” (Matthew 17:21). The Lord states a fact, not a suggestion. Some spiritual challenges will only yield to combined prayer and fasting.


Prayer: Drawing on God’s Power

• Recognizes we fight “not against flesh and blood” (Ephesians 6:12).

• Invites God’s direct intervention (Psalm 50:15).

• Releases authority Jesus already gave (Luke 10:19).

• Opens us to specific guidance (Jeremiah 33:3).


Fasting: Declaring Dependence and Urgency

• Weakens the flesh so the spirit can listen (Galatians 5:16–17).

• Models the early church’s pattern: “they fasted and prayed, and laid their hands on them” (Acts 13:3).

• Shifts focus from earthly provision to heavenly help (Matthew 6:16-18).

• Adds weight to intercession—Ezra 8:23; “He answered our prayer.”


Why They Work Together

• Prayer aligns our will with God’s; fasting subdues competing desires.

• Combined, they sharpen spiritual discernment (Daniel 9:3, 20-23).

• They demonstrate faith that God alone breaks “strongholds” (2 Corinthians 10:4).


Practical Steps for Today

1. Identify the specific spiritual obstacle—habitual sin, oppression, family bondage.

2. Set a period of fasting—meal, day, or longer as health allows. Replace mealtime with worship and the Word.

3. Pray Scripture aloud:

– “The Lord rebuke you, Satan.” (Zechariah 3:2)

– “Greater is He who is in you.” (1 John 4:4)

4. Stand in Christ’s authority. Mark 11:24: “whatever you ask for in prayer, believe that you have received it.”

5. Maintain normal humility; don’t broadcast the fast (Matthew 6:17-18).

6. Conclude with thanksgiving, expecting tangible change.


Encouragement from Other Passages

Mark 9:29 repeats the principle.

Joel 2:12-13 links fasting with wholehearted return to God and promised restoration.

Acts 14:23 shows leaders appointed after “prayer with fasting,” confirming direction.


Living Expectantly

The Lord’s statement in Matthew 17:21 is timeless. Prayer and fasting are not rituals to earn favor; they position us to receive God’s decisive, supernatural answer. When the battle is fierce and ordinary efforts fail, Scripture assures us this paired discipline still drives out “this kind” today.
