Luke 17:6 (KJV)

What does Luke 17:6 mean?

Luke 17:6 describes Jesus telling his followers that even a very small amount of faith—like a mustard seed—could accomplish what seems impossible, such as commanding a tree to uproot itself and be planted in the sea. The verse uses vivid imagery to show that genuine faith, no matter how small, has great potential.

In this scene, Jesus is speaking to his disciples, responding to their request for increased faith. The "sycamine tree" he mentions was known for its deep roots, making the idea of moving it especially striking. The focus is not on the size of faith itself, but on the power and effectiveness of faith when it is real, even if it seems tiny.

The Greek behind Luke 17:6

• πίστις (pistis, G4102): This word means "faith" or "trust." Here, Jesus highlights that it is not the amount of faith that matters, but its presence and authenticity.
• κόκκος (kokkos, G2848): Translated as "grain," this refers to something very small, emphasizing the minimal size needed for faith to be effective.
• συκάμινος (sykaminos, G4807): This is the "sycamine tree," a tree known for its strong, deep roots. Mentioning this tree underlines the difficulty of the task, making the point about faith's power even clearer.
• ὑπακούω (hypakouō, G5219): Translated as "obey," this word carries the sense of something responding to a command. The verse stresses that even nature would respond to faith-filled words.

Why Luke 17:6 matters

• Luke 17:6 clears up the common misunderstanding that faith must be large or impressive to be effective; Jesus instead points to the quality and presence of faith, not its quantity.
• The verse emphasizes that faith is not about personal power or magic, but about trust in God’s ability to do what seems impossible.
• This teaching connects to the wider passage, where Jesus is instructing his disciples about forgiveness and humility, showing that faith is central to living out his teachings.
