Faith That Moves Mountains: The Power of Prayer and Fasting
"When they were come to the multitude, there came to him a certain man, kneeling down to him, and saying, Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water. And I brought him to thy disciples, and they could not cure him. Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me. And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour. Then came the disciples to Jesus apart, and said, Why could not we cast him out? And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you. Howbeit this kind goeth not out but by prayer and fasting." - Matthew 17:14-21

In Matthew 17:14-21, we encounter a poignant scene that resonates deeply with our human experience: a father, desperate for relief for his tormented son, kneels before Jesus, pleading for mercy. The father describes his son’s condition as ‘lunatick’ and ‘sore vexed,’ indicating not only physical afflictions but also a spiritual bondage that has left him vulnerable, even to the point of self-harm. This desperate moment highlights a recurring theme throughout scripture—the collision between human frailty and divine power.
The father’s plea is a vivid reminder of our own struggles; we face various forms of affliction—be it in our health, relationships, or spiritual lives. Like the father, we sometimes find ourselves in situations where solutions seem out of reach. His choice to kneel signifies humility and recognition of his limitations. It serves as a powerful example that in our lowest moments, when we have exhausted all earthly options, we must turn to Jesus, who is the ultimate healer and deliverer.
As Jesus interacts with the father, He expresses a poignant disappointment: ‘O faithless and perverse generation, how long shall I be with you? how long shall I suffer you?’ This response reverberates not just as a rebuke to the people of that time but as a call to introspection for us today. It beckons us to examine our own belief. Are we living in faith, trusting God’s capabilities, or are we succumbing to despair and doubt?
When Jesus commands for the boy to be brought to Him, a miraculous transformation occurs. He rebukes the devil, and in that moment, the child is radically changed. This action reveals two significant truths about Jesus: His authority over spiritual forces and His compassion for suffering humanity. Jesus’ ability to heal instantly illustrates that no condition is too severe for Him to address.
Following this miracle, the disciples come to Jesus privately, confused as to why they were unable to cast out the demon themselves. His reply addresses a significant spiritual principle: ‘Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.’ Here, Jesus juxtaposes the power of faith—no matter how small—with our inherent limitation of unbelief.
The mustard seed becomes a powerful metaphor for faith. Its small size suggests that we don’t need to possess enormous amounts of faith; instead, we must focus on the object of our faith—Jesus Himself. When we align our belief with His power, mountains become movable. But Jesus reinforces the necessity of prayer and fasting: ‘Howbeit this kind goeth not out but by prayer and fasting.’ This reveals another layer of spiritual warfare—certain challenges require more than faith alone; they demand disciplined prayer and deep intimacy with God.
Prayer is the avenue through which we commune with the Lord and align our will with His. It fortifies our spirits, prepares us for battle, and invites God’s intervention into our circumstances. Fasting, on the other hand, is a form of sacrifice, showing God that we’re serious about seeking His help and guidance. Incorporating these practices into our lives transforms our faith, shining light on areas where we may still harbor doubt.
As we reflect on this passage, let us ask ourselves: How is our faith today? Are we approaching God with the desperation of the father? Are we persistent in prayer and fasting, seeking His will above our desires? We are invited to surrender our struggles to Jesus, who not only has the power to heal and deliver but also desires a relationship with us. Let us cultivate a faith that moves mountains, aware that with God, nothing is impossible.

Matthew 17:14-21
Matthew 17:14-21 - "When they came to the crowd, a man approached Jesus and knelt before him. "Lord, have mercy on my son," he said. "He has seizures and is suffering greatly. He often falls into the fire or into the water. I brought him to your disciples, but they could not heal him." "You unbelieving and perverse generation," Jesus replied, "how long shall I stay with you? How long shall I put up with you? Bring the boy here to me." Jesus rebuked the demon, and it came out of the boy, and he was healed at that moment. Then the disciples came to Jesus in private and asked, "Why couldn't we drive it out?" He replied, "Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there,' and it will move. Nothing will be impossible for you." In some manuscripts, verse 21 is added as "But this kind does not go out except by prayer and fasting.""
