Luke 17:5 · KJV


Context

3

Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him.

4

And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him.

5

And the apostles said unto the Lord, Increase our faith.

6

And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.

7

But which of you, having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat?


Commentary

KJV Study Commentary
The apostles respond: 'Lord, Increase our faith' (Κύριε, πρόσθες ἡμῖν πίστιν). Jesus' demanding teachings on forgiveness (vv.3-4) prompt this request. The verb 'prostithēmi' (πρόσθες, increase/add to) assumes faith is quantifiable. Jesus corrects this misunderstanding: faith's power is not its size but its object. 'If ye had faith as a grain of mustard seed' (v.6)—the smallest seed—'ye might say unto this sycamine tree, Be thou plucked up...and it should obey you.' The point is not faith's amount but its focus: even tiny faith in the omnipotent God accomplishes impossibilities. The disciples seek more faith; Jesus says use the faith you have.

Historical & Cultural Context

Mustard seeds were proverbially tiny (see Luke 13:19). Sycamine trees (black mulberry) had deep root systems, making them difficult to uproot—hence the illustration's power. Jesus' teaching on faith's power appears throughout the Gospels (Matthew 17:20, 21:21, Mark 11:22-24), emphasizing prayer's effectiveness through trust in God. The disciples' request for increased faith reveals their misunderstanding—they sought something to add to themselves rather than recognizing faith as simple trust in God's character and promises.

Reflection Questions

  1. How does Jesus' teaching about faith's quality versus quantity challenge contemporary emphasis on strong versus weak faith?
  2. What would change in your prayer life if you truly believed that small faith in a great God can move mountains?
