Luke 17:6 – “He replied, ‘If you have faith as small as a mustard seed, you can say to this mulberry tree, “Be uprooted and planted in the sea,” and it will obey you.'”
Extended Explanation of the Verse
In this verse, Jesus is responding to the apostles’ request for more faith. Instead of giving them a lecture on how to build faith, He points out that the amount of faith isn’t the most important thing. Even faith as tiny as a mustard seed—a small, seemingly insignificant seed—can achieve the impossible when it’s rooted in God. The image of commanding a mulberry tree to uproot and plant itself in the sea is an extreme illustration meant to convey that what seems impossible for humans is possible with God.
Jesus is teaching that it’s not about the size of your faith but the object of your faith. A little faith placed in a great God can accomplish incredible things. Even if you feel like your faith is weak or small, when you trust in God, He can do what seems beyond human ability.
Historical Context
Mustard seeds were common in the region and well-known for their tiny size. Jesus often used everyday agricultural examples to teach spiritual truths, so His audience would have understood the significance of this analogy. The mulberry tree was also familiar to them—its roots were known for being deep and hard to remove. The idea of a tree being uprooted and planted in the sea would have sounded absurd, but that’s the point. Jesus was showing that God’s power is limitless, and even the smallest bit of faith in Him can achieve the unthinkable.
In Jewish thought, faith was often tied to obedience and trust in God’s promises. However, many people saw miracles and great acts of faith as something reserved for prophets or holy leaders. Jesus is turning this idea on its head by teaching that even ordinary people, with just a small amount of faith, can experience God’s power.
Theological Implications
This verse teaches that faith is not measured by how much you have but by who you place it in. The power of faith comes from God, not from the person exercising it. A mustard seed of faith is enough because it connects you to the limitless power of God. Theologically, this reinforces the idea that God is sovereign and able to do the impossible, but it also highlights the role of trust. When believers trust God, even with small faith, He is faithful to act according to His will.
It also shows that faith is dynamic. As believers experience God working through their small steps of faith, their trust in Him grows. This verse encourages believers not to be discouraged by the size of their faith but to focus on the greatness of God.
Literary Analysis
The verse uses hyperbolic imagery—Jesus often employed exaggeration to make a point. The mustard seed is one of the smallest seeds, and the idea of a deeply rooted mulberry tree being planted in the sea is intentionally extreme. By using this imagery, Jesus emphasizes that no obstacle is too big when faith is placed in God.
The structure of the verse is simple but powerful. It begins with a conditional statement—“if you have faith”—and then presents an outcome that defies logic. This contrast between small faith and large results is meant to highlight God’s ability to work through those who trust Him.

What This Verse Means for Today’s Christian
For today’s believers, this verse is a reminder that faith doesn’t have to be perfect or large for God to work. Many Christians struggle with doubt or feel inadequate because they think their faith isn’t strong enough. Jesus’ words encourage us to trust God, even when our faith feels small. It’s not about how confident we feel but about taking that step of trust in God’s power and promises.
This verse also teaches that faith involves action. The apostles weren’t just called to sit and believe—they were called to exercise their faith by trusting God to do what seemed impossible. Whether it’s forgiving someone, facing a difficult challenge, or stepping into an unknown future, faith calls us to trust God and take action, even when we don’t see the outcome.
How This Verse Relates to a Loving God
God’s love is shown in the way He honors even the smallest amount of faith. He doesn’t expect believers to have perfect or unshakable faith from the start. Instead, He meets them where they are, nurturing their growth as they learn to trust Him more. God’s love is patient—He works through believers’ weaknesses and doubts to bring about His purposes.
This verse also reflects God’s desire for His children to experience His power in their lives. He doesn’t want them to be weighed down by fear or inadequacy. His invitation to trust Him, even with mustard-seed faith, shows that He is willing to do great things for those who rely on Him.
How This Verse Connects to Jesus Christ
Jesus is the object of true faith. Throughout His ministry, He demonstrated that faith in Him could lead to healing, forgiveness, and salvation. In many of His miracles, it was the individual’s faith in Him that made the difference, such as the woman who touched His cloak and was healed (Mark 5:34). Jesus consistently pointed people to the importance of trusting in Him, not in their own abilities.
Ultimately, Jesus’ death and resurrection are the foundation of Christian faith. By trusting in what He accomplished on the cross, believers receive salvation (Ephesians 2:8-9). Just as Jesus taught that even a mustard seed of faith could move mountains, the faith that brings salvation doesn’t have to be perfect—it just has to be placed in Him.
