Humility is the strongest armor, forged of all virtue and feared by demons and satan.

The Power of Great Faith

Great faith, when rooted in truth, is incredibly powerful because it aligns the believer with reality, divine principles, and ultimate purpose. This kind of faith acts as a transformative force, capable of overcoming obstacles, empowering individuals, and influencing the world around them. When a person’s faith is grounded in truth:

  1. It is steadfast and unshakable.
  2. It unlocks divine power and aligns with God’s will.
  3. It gives courage, hope, and joy.
  4. It transforms lives and communities.
  5. It provides eternal perspective and peace.

Truth-based faith is not merely optimism or wishful thinking—it is an active trust in God’s character, promises, and plan. This kind of faith moves mountains, changes hearts, and stands as a light in the darkness, reflecting the boundless power of the truth it is built upon. Here’s how and why great faith based on truth is so powerful: 

Unshakable and Unlocks Divine Power

1. Faith Anchored in Truth is Unshakable

  • Why: Faith based on truth is not blind or baseless but grounded in reality, reason, and evidence. It finds its foundation in God, the ultimate source of truth, as well as in divine promises and immutable principles.
  • Impact: Such faith remains steadfast even in the face of trials, doubts, or opposition. Like a house built on rock, it cannot be easily shaken by life’s storms (Matthew 7:24-25).

2. Unlocks Divine Power

  • Why: Truth-based faith aligns a person with God’s will and unleashes His power in their life. When faith is grounded in truth, it trusts in the promises of God, opening the way for His intervention and miracles.
  • Impact: Mountains can be moved, both literally and figuratively, when faith aligns with truth (Matthew 17:20). This enables individuals to accomplish what seems impossible.

Courage, Resilience, and True Freedom

3. Gives Courage and Resilience

  • Why: Faith in truth provides clarity about one’s identity, purpose, and destiny. Knowing the truth of God’s sovereignty and love gives confidence to face life’s challenges with courage and determination.
  • Impact: This faith sustains individuals through suffering, loss, and adversity, knowing that their struggles are temporary and serve a greater purpose.

4. Fosters True Freedom

  • Why: Jesus said, “The truth will set you free” (John 8:32). Faith based on truth liberates individuals from fear, doubt, and the lies of the world or spiritual forces.
  • Impact: This freedom empowers individuals to live boldly, unencumbered by the chains of sin, guilt, or fear of the unknown, enabling them to focus on their divine calling.

Transformation and Eternal Purpose

5. Creates Transformational Influence

  • Why: Faith in truth radiates authenticity and integrity, drawing others to the light of that truth. It inspires trust and respect in others, influencing hearts and minds.
  • Impact: This kind of faith can transform families, communities, and even nations by encouraging justice, love, and reconciliation.

6. Connects with Eternal Purpose

  • Why: Truth-based faith is tied to eternal realities, not just temporary circumstances. It understands that life’s ultimate goal is unity with God and the fulfillment of His plans.
  • Impact: This perspective gives faith enduring power, as it is not deterred by worldly setbacks or fleeting challenges. It focuses on the bigger picture of God’s eternal plan.

  • Impact: Heroes of faith throughout history—such as Abraham, Moses, and Paul—accomplished extraordinary acts not because of their strength but because of their faith in God’s truth.

10. Aligns with Divine Truth

  • Why: Faith rooted in truth harmonizes with God’s reality, ensuring that it is not misplaced or misguided.

How Great Faith is Effective Against Demons and Evil in General

Great faith is a supernatural trust and confidence in God—believing firmly in His power, His promises, and His goodness, no matter the circumstances. It goes beyond simply believing that God exists; it is complete surrender to His will, assurance of His victory, and bold reliance on His authority. Demons are terrified of great faith because it removes fear, doubt, and hesitation, leaving no foothold for the enemy. Great faith is one of the most powerful spiritual weapons in existence.

Great Faith Destroys the devil's strategy of fear and doubt

One of Satan’s primary tactics is to whisper lies like, “God won’t help you,” “This is impossible,” or “You’re alone.” Great faith immediately rejects these lies and stands firm in God’s truth.

  • Great faith shuts down anxiety and despair – Where demons sow fear, great faith clings to God’s promises of protection and provision.
  • It believes in victory before it’s visible – Even when all seems lost, great faith declares that God will triumph.
  • It silences the devil’s lies – The enemy’s power relies on doubt, but faith says, “I trust God, no matter what.”

Example: David faced Goliath with great faith, knowing God would deliver him, despite the odds (1 Samuel 17). His unwavering faith defeated fear and crushed the enemy.

Great Faith breaks the chains of hopelessness and despair

Demons love to drag people into hopelessness, making them believe that their situation is beyond saving. Great faith shatters hopelessness and opens the door to miracles.

  • Great faith expects God to act – While demons whisper, “Nothing will change,” great faith knows God can do the impossible.
  • It perseveres through long battles – When others give up, great faith holds on without wavering, weakening the enemy’s persistence.
  • Great faith allows the miraculous to happen – Many miracles in Scripture happened because someone dared to believe without limits.

Example: The woman with the hemorrhage (Mark 5:34) was healed because her great faith believed that even touching Jesus’ garment was enough.

Great Faith makes prayer and spiritual warfare unstoppable

Prayer backed by great faith is extremely dangerous to demons. Faithless prayers are weak, but great faith prays with authority, knowing heaven listens.

  • Great faith prays boldly – It doesn’t say, “Maybe God will help,” but “God is already moving.”
  • It strengthens prayers of deliverance and healing – Many exorcists and saints report that great faith weakens demons and forces them to flee.
  • Faith turns spiritual warfare into victory – Demons cannot hold ground where great faith commands in the name of Jesus.

Example: The centurion’s great faith (Matthew 8:10) led Jesus to heal his servant from a distance, proving that faith itself is a weapon against sickness and evil.

Demons often attack through discouragement, confusion, and spiritual dryness. Great faith keeps the soul anchored in truth, no matter the storm.

  • Great faith keeps you standing when under attack – While others panic, a person of great faith remains calm and confident.
  • It prevents temptation from becoming sin – Faith knows God provides a way out of every temptation (1 Corinthians 10:13).
  • It keeps the focus on eternity – Instead of being shaken by worldly struggles, great faith keeps the soul fixed on Heaven.

Example: Job endured extreme suffering, but his great faith declared, “Though He slay me, yet will I trust Him” (Job 13:15). This crushed Satan’s attempt to make him curse God.

Satan works to weaken faith across entire communities, spreading fear, compromise, and spiritual lukewarmness. Great faith, even in one person, can ignite revival and block the enemy’s influence.

  • Great faith inspires others – Bold faith awakens courage in those around you, making it harder for the devil to divide and conquer.
  • It restores families – Where the devil has sown division, great faith believes in healing and reconciliation.
  • It protects churches and communities from compromise – While the enemy pushes for watered-down truth, great faith defends God’s Word without fear.

Example: St. Joan of Arc’s great faith led her to rally an entire nation, defeating enemies through both physical and spiritual battles.

Great Faith as a powerful Armor against evil

  1. Demons thrive on fear and doubt—great faith shuts them down.
  2. It defeats hopelessness by believing in God’s power to act.
  3. It empowers prayer and spiritual warfare, making them highly effective.
  4. It shields the soul during spiritual attacks and temptations.
  5. It protects and revives families, churches, and nations, blocking the enemy’s plans.

How to strengthen Faith

  • Pray daily for an increase of faith, especially in difficult times.
  • Meditate on Scripture stories of miraculous faith (like Hebrews 11).
  • Receive the Sacraments frequently (the Eucharist and Confession nourish faith).
  • Act on faith by stepping out in trust, even when afraid.
  • Reject doubts immediately by affirming God’s promises.


Great faith is the devil’s defeat. Those who cultivate great faith become fearless, victorious, and impossible for demons to discourage, leading others into the light of God’s power.
