Matthew 17:19's link to faith, doubt?
How does Matthew 17:19 connect with other scriptures about faith and doubt?

Setting the scene in Matthew 17:19

“Afterward the disciples came to Jesus privately and asked, ‘Why couldn’t we drive it out?’” (Matthew 17:19)


Immediate answer from Jesus (v. 20)

“Because you have so little faith… if you have faith the size of a mustard seed… nothing will be impossible for you.”


Key themes to notice

• Failure traced to “little faith,” not to technique

• Private conversation shows teachability and honest self-examination

• Promise that even tiny, real faith releases God’s power


Echoes of the same lesson in other moments with Jesus

Matthew 14:31 — Peter sinks after walking on water: “You of little faith, why did you doubt?”

Matthew 21:21 — Fig-tree incident: “If you have faith and do not doubt… it will happen.”

Luke 17:5-6 — Apostles ask for more faith; Jesus points again to the mustard seed


Broader New Testament reinforcement

Mark 11:22-24 — Faith plus “no doubt in his heart” moves a mountain into the sea

James 1:6 — Prayer must be “in faith, without doubting” or the petitioner is “like a wave of the sea”

John 20:27 — Thomas invited to stop doubting and believe

Hebrews 11:1, 6 — Faith defined as assurance; without it God cannot be pleased


Shared thread running through these passages

• Doubt disrupts the flow of divine power

• God does not demand great faith, only genuine faith

• Faith grows as it is exercised; the disciples’ question in Matthew 17:19 marks the start of that growth


Practical take-aways for disciples today

• Face moments of failure honestly, just as the disciples did

• Trace spiritual setbacks to the root of unbelief, not merely to outward methods

• Nourish faith by recalling God’s track record (Hebrews 11)

• Speak and pray from a convinced heart, expecting God to act (Mark 11:24)

• Celebrate even “mustard seed” breakthroughs, which confirm that nothing is impossible with God
