Luke 17:5 and Hebrews 11:1 on faith?
How does Luke 17:5 connect with Hebrews 11:1 on faith's definition?

Setting the Scene—The Disciples’ Plea

Luke 17:5: “The apostles said to the Lord, ‘Increase our faith!’ ”

• Jesus had just warned them about stumbling blocks and commanded repeated forgiveness (Luke 17:1-4).

• Realizing the weight of His words, the apostles sensed their own insufficiency and cried out for a larger measure of faith.

• Their request shows faith is not static; it can and should grow (cf. 2 Thessalonians 1:3).


Faith Defined—Hebrews 11:1 Unpacked

Hebrews 11:1: “Now faith is the assurance of what we hope for and the conviction of what we do not see.”

• Assurance—πόστασις (hypostasis): a firm, underlying reality; faith treats God’s promises as present fact.

• Conviction—ἔλεγχος (elegchos): proof that persuades; faith brings unseen truths into clear focus.

• Faith therefore deals both with future hope and present certainty (cf. Romans 8:24-25; 2 Corinthians 5:7).


Connecting Luke 17:5 with Hebrews 11:1

• The disciples asked for “more” of the very thing Hebrews defines. They wanted deeper assurance and stronger conviction.

• Luke shows faith’s dynamic nature—quantity can increase. Hebrews shows faith’s qualitative nature—what it actually is.

• Jesus’ immediate reply (Luke 17:6) illustrates Hebrews 11:1: even “faith as small as a mustard seed” contains real substance and power, because its object is God, not the believer.

Hebrews 11 then lists examples (Abel, Noah, Abraham) that answer the disciples’ longing—lives that turned unseen promises into tangible obedience (Hebrews 11:7-10).

• Both passages teach that faith rests on God’s character and word:

– Luke: Jesus, the living Word, invites trust.

– Hebrews: God’s spoken word framed the universe (Hebrews 11:3); thus His promises are rock-solid.


Implications for Growing Faith Today

• Ask boldly—God welcomes prayers like Luke 17:5 (cf. Mark 9:24; James 1:5-6).

• Anchor every hope in Scripture’s promises; let Hebrews 11:1 shape the definition you carry into daily life.

• Feed faith by hearing the Word (Romans 10:17) and acting on it—obedience reinforces conviction.

• Remember: even a “mustard-seed” measure, rightly placed, moves mountains because the power is God’s (Matthew 17:20).

The disciples’ request in Luke 17:5 meets its biblical explanation in Hebrews 11:1: faith is measurable, growable assurance and conviction in the unseen promises that God guarantees.
