Matthew 17:19-21 is about the power of faith and prayer, emphasizing that even a small amount of faith can move mountains, and that certain spiritual obstacles can only be overcome through prayer combined with faith.
19 Then the disciples came to Jesus privately and said, “Why could we not cast it out?”
20 He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”
21 But this kind never comes out except by prayer and fasting.”

Setting the Scene for Matthew 17:19-21
In Matthew chapter 17, we find Jesus on a mountain with three of his disciples: Peter, James, and John. The scene is set on a high mountain, likely Mount Hermon or Mount Tabor, with a breathtaking view of the surrounding landscape. The disciples are with Jesus, witnessing a momentous event about to unfold before them.
Jesus takes Peter, James, and John up the mountain with him for a specific purpose. As they reach the summit, Jesus is transfigured before them, his face shining like the sun, and his clothes becoming as white as light. Suddenly, Moses and Elijah appear, talking with Jesus. The disciples are in awe, witnessing this incredible moment of divine revelation.
In the midst of this transfiguration, a voice from heaven speaks, affirming Jesus as the beloved Son of God. Overwhelmed by the experience, the disciples fall facedown in fear. This scene on the mountain serves as a powerful confirmation of Jesus’ identity and mission, preparing the disciples for the challenges that lie ahead.
What is Matthew 17:19-21 about?
This verse from the book of Matthew holds a powerful message about the importance of faith, prayer, and fasting in our spiritual lives. It reminds us that when we have unwavering faith in God, we can overcome seemingly insurmountable obstacles just like moving mountains. Faith is a potent force that can bring about miraculous transformations and breakthroughs in our lives. However, faith is not a stagnant belief; it needs to be nurtured and strengthened through prayer and fasting.
Prayer and fasting are spiritual disciplines that deepen our connection to God and increase our reliance on Him. Through prayer, we communicate with God, pour out our hearts, and seek His guidance and intervention. Fasting, on the other hand, involves denying ourselves physically to focus on spiritual nourishment and growth. It helps us discipline our bodies and sharpen our spiritual senses. When we combine faith with the practices of prayer and fasting, we align ourselves with God’s will and tap into His unlimited power and wisdom.
So, as you navigate through life’s challenges and uncertainties, remember the profound truth in this verse. Reflect on how your faith, prayer life, and fasting routines can be strengthened to move mountains in your life. Take time to cultivate a deeper relationship with God through these spiritual disciplines, and watch as your faith grows stronger, enabling you to face obstacles with courage and conviction.
Understanding what Matthew 17:19-21 really means
In Matthew 17:19-21, we find a powerful lesson on faith and prayer taught by Jesus to his disciples. The context of this passage is crucial, occurring right after Jesus heals a demon-possessed boy that the disciples were unable to help. When the disciples inquire about their failure, Jesus responds by highlighting the significance of faith. He tells them, “Because of your little faith,” pinpointing that their lack of unwavering belief was the root cause of their inability to cast out the demon. This phrase underscores the essential role faith plays in the life of a believer.
Jesus further illustrates the potency of faith by using the analogy of a mustard seed, one of the tiniest seeds known. He emphasizes that even faith as small as a mustard seed can move mountains. This vivid imagery conveys the idea that genuine, albeit small, faith can lead to extraordinary outcomes. The statement, “You can say to this mountain, ‘Move from here to there,’ and it will move,” symbolizes the immense power that faith holds in overcoming seemingly insurmountable obstacles in our lives.
The assurance that “nothing will be impossible for you” with faith serves as a beacon of hope for believers facing challenges today. In a world filled with uncertainties and trials, this passage offers a comforting reminder that faith can be a source of strength and resilience. It encourages individuals to nurture their faith, no matter how small it may seem, as it has the potential to bring about significant transformations.
Drawing parallels to other biblical passages such as Matthew 21:21-22, Mark 9:23, and Hebrews 11:1, we see a consistent theme emphasizing the power of faith in achieving the impossible. These verses reinforce the idea that belief in the unseen can lead to miraculous outcomes. By reflecting on these teachings and incorporating them into our lives, we can find solace and empowerment in knowing that faith has the ability to move mountains.
An anecdote can further illuminate the impact of faith in real-life situations. Imagine a person grappling with a severe illness, seeking healing through medical interventions without success. Through fervent prayer and unwavering faith, they experience a miraculous recovery that defies medical explanation. This narrative exemplifies how faith can bring about extraordinary changes, echoing the message conveyed in Matthew 17:19-21.
To apply the teachings of this passage, believers are encouraged to introspect on areas of their lives where they feel overwhelmed or powerless. By nurturing their faith through prayer, studying scripture, and engaging with a community of believers, they can witness the transformative power of even a small amount of genuine faith. Trusting in God’s ability to overcome obstacles, no matter how daunting they may appear, can instill hope and resilience in the face of adversity.
In conclusion, the lesson on faith and prayer in Matthew 17:19-21 serves as a timeless reminder of the boundless possibilities that faith can unlock. By embracing this teaching, believers can find strength, hope, and assurance in knowing that with God, nothing is impossible.

This kind of faith is unwavering even in the face of challenges, doubts, and uncertainties.
Our faith in God is not passive but active, requiring us to take steps of obedience and align our actions with our belief in His sovereignty. It involves fervent prayer, fasting, and seeking Him with all our hearts, knowing that our faith coupled with these actions can lead to transformative and miraculous outcomes. Through this kind of faith, we demonstrate our dependency on God and our willingness to surrender control to Him, allowing His power to manifest in our lives.
