芥菜種的信心：倚靠上帝成就不可能

Jun 26, 2026

Devotional

Day 1: When the Mountain Won’t Move

A father kneels, desperate for his son’s healing. The disciples, armed with Jesus’ earlier promises, try to drive out the demon but fail. Their question—“Why couldn’t we?”—reveals a faith tangled in self-reliance. Jesus redirects them: faith isn’t about mustering personal power but surrendering to the God who transforms mustard-seed smallness into mountain-moving impossibility. True faith looks beyond visible resources to the One who resurrects the dead. [32:16]

“Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.” (Matthew 17:20, NIV)

Reflection: Where have you been striving in your own strength, mistaking ability for faith? How might releasing control to God’s unseen power change your approach to an impossible situation?

Day 2: Failure as a Doorway to Dependence

The disciples’ humiliation—failing to heal a boy after Jesus had given them authority—exposes their misplaced confidence. They assumed past success guaranteed future results. Jesus names their “little faith” not as a lack of effort but a failure to anchor in daily dependence. Brokenness becomes the threshold where self-sufficiency dies and God’s power begins. [34:45]

“But he said to me, ‘My grace is sufficient for you, for my power is made perfect in weakness.’ Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.” (2 Corinthians 12:9, NIV)

Reflection: What recent disappointment or failure might God be using to pry your grip from self-reliance? How can you lean into His strength in that weakness today?

Day 3: The Unlikely Vessels of Heaven’s Power

Jesus, the criminal-turned-Messiah, upends expectations. The disciples wanted a king who validated their competence; God sent a Savior who works through fishermen, tax collectors, and crucified rebels. Faith thrives not in resumes or reputation but in surrendered hearts. The smaller the seed, the more clearly God’s glory grows through it. [52:00]

“But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. God chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are.” (1 Corinthians 1:27–28, NIV)

Reflection: Where do you feel “unqualified” or inadequate? How might God want to use that very insecurity to display His strength?

Day 4: The Cross as the Only Measure of True Power

The disciples resisted Jesus’ talk of suffering, clinging to visions of earthly glory. Yet the crucifixion—the ultimate “failure”—became the hinge of salvation. Faith that moves mountains isn’t about avoiding pain but trusting the God who redeems it. True power hides in the paradox of a crucified King. [01:06:19]

“For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.” (1 Corinthians 1:18, NIV)

Reflection: How does your definition of “victory” clash with the way of the cross? Where is God inviting you to trust His upside-down economy of power?

Day 5: Letting Go of the World’s Yardstick

The disciples measured faith by visible outcomes: demons cast out, crowds impressed. Jesus redefines faith as allegiance to the unseen Gardener who grows seeds into trees. When we stop evaluating God by human standards, we make space for Him to work beyond our formulas—in quiet miracles, slow transformations, and unexpected people. [01:14:42]

“For my thoughts are not your thoughts, neither are your ways my ways,” declares the Lord. “As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.” (Isaiah 55:8–9, NIV)

Reflection: What “measuring stick” (success, recognition, visible impact) have you been using to evaluate your faith? How can you release it to embrace God’s hidden work today?

Sermon Summary

马太的叙事把这段失败的赶鬼放在两次受难复活宣告之间，并且夹着登山变像，正把门徒的“信”照出来。门徒的追问“为什么我们不能赶出那鬼？”已经预设自己应该能行，因为彼得刚在前一章认信，主也应许“把天国的钥匙给你们”，捆绑和释放都带着权柄。门徒因此盼见弥赛亚的荣耀与自己分得的能力，结果在实际争战里靠着“我们”的把握与方法，碰壁了。耶稣的判词很直白：“你们的信心小”，并命令“把他带到我这里来”，把失败的根源从技巧问题拉回到信的对象。

芥菜种的比喻不是鼓励“信得小也可以”，而是揭开一种从极小到极大的反差：眼前是一粒最小的种子，将来却长成大树；现在看像不可能，到了上帝手里却成为可能。芥菜种的信心不是评估手上有什么资本，而是越过现状，看见上帝要成就什么，把“山”交给那位移山的主。这信心不是把上帝纳入人的计划，而是在人所不能里，安放在上帝能。

门徒对受苦宣告的本能排斥，和彼得在山上“这里真好，要搭三座棚”的冲动，出卖了他们心底的弥赛亚想象：要荣耀的君王，不要受苦的仆人。可是在复活之后，使徒只夸十字架，甘心作最小的，正是芥菜种的路。上帝给恩赐、给经验、给位置，但一旦恩赐变成自我支撑，服事就从“把人带到耶稣面前”变成“把人带到我的能力前”，失败几乎是注定的。

因此，真正的信心先放下世界的量尺。履历、名校、技巧、话术都不是信心的对象；主耶稣自己在世按世界标准并不“合格”，却是神的儿子，和罪人坐席，担当“罪犯”的十字架。传福音与服事的果效，归根到底在于主的同在与旨意；上帝若愿意，最简单的一句话也能叫人归向基督。芥菜种的信心，就是在每一步学放手、学仰望、学顺服，让上帝把小变大，把看不见的带到眼前。

Key Takeaways

1. 小信错在信的对象 [32:16] 门徒的“为什么我们不行”暴露的是依靠自己、盼望权限能盖章的心态。耶稣要的不是更熟练的驱魔配方，而是“把他带到我这里来”的转向。信心的关键不在于手里握有什么，而在于眼目定睛谁。对象若对，能力就回到位。 [32:16]
2. 芥菜种翻转不可能 [48:29] 芥菜种的重点是反差，从最小到极大，从看似不可能到真实成就。这样的信心敢把“山”交给上帝，而不是把上帝塞进人的框架。眼前的渺小不是结局，上帝的作为才是尺度。 [48:29]
3. 别用世界的履历量主 [01:02:22] 资历、名气、经验可供参考，却无法说明一个人怎样认识、信服、依靠上帝。把信心押注在“已经拥有”的身上，只会限制祷告与顺服的想象空间。信心更该问的是：他与上帝之间的敬畏、挣扎与顺从到了哪里。 [62:22]
4. 走十字架成最小的 [01:06:19] 弥赛亚的路经过受苦，门徒后来只夸十字架，就是把自己放到“最小”的位置。芥菜种的路不是自抬身量，而是给上帝空间来结出百倍的果子。放下荣耀，才真正腾出信靠的余地。 [66:19]
5. 服事就是把人带主前 [58:57] 恩赐若成为倚靠，就会把人带到人的能力面前；恩赐若归回主手，就会把人直接带到耶稣面前。真正的果效不在技巧的繁复，而在主在场的权能与怜悯。对象一换，事工的成败标准也被翻新。 [58:57]

Bible Study Guide

Bible Reading
- Matthew 17:14-20 (ESV)
The healing of a boy with a demon, the disciples’ failure, and Jesus’ teaching on faith.

Observation questions

In Matthew 17:19, the disciples ask Jesus, “Why could we not cast it out?” What earlier event in Matthew 16:13-20 might have led them to assume they should have succeeded?
How does Jesus’ response in Matthew 17:20 (“if you have faith like a grain of mustard seed…”) contrast with the disciples’ focus on their own ability? [34:45]
The sermon mentions Peter’s reaction to the Transfiguration (“Let us make three tents here”) and his resistance to Jesus’ prediction of suffering. How do these moments reveal a misunderstanding of the Messiah’s mission? [41:29]
What does the mustard seed analogy (Matthew 13:31-32) emphasize about God’s work versus human expectations?

Interpretation questions

Why did Jesus rebuke the disciples’ faith as “small” even though they had successfully cast out demons before (Matthew 10:8)? How might their question (“Why could we not…”) expose misplaced confidence? [37:08]
The sermon argues that the mustard seed’s power lies in its “reversal of impossibility,” not its size. How does this redefine what it means to trust God in seemingly hopeless situations? [48:29]
Jesus commanded, “Bring him to Me” (Matthew 17:17). How does this redirect the disciples’ focus from their own methods to His authority?
Why might worldly metrics (e.g., resumes, skills) actually hinder reliance on God’s power? [01:02:22]

Application questions

When have you relied on past successes, spiritual gifts, or credentials (e.g., ministry experience, knowledge) instead of directly depending on Christ? What practical step could help you shift from “I can do this” to “God can do this”? [58:57]
The sermon warns against valuing “glory” over the cross. Where do you feel resistance to God’s methods (e.g., humility, suffering, waiting) in your life? How might embracing “smallness” (like the mustard seed) free you? [01:06:19]
Jesus prioritized bringing the boy to Himself over perfecting the disciples’ techniques. In your relationships or ministry, are you more focused on showcasing your abilities or pointing others to Christ? Give an example.
The sermon says, “God’s simplest word can bring someone to Christ if He wills.” How might this truth change your approach to sharing the gospel with someone who seems “unreachable”? [01:09:43]
What “impossible” situation (a strained relationship, a persistent sin, a closed door) do you need to entrust to God’s “mustard seed” logic today? Write down one action to surrender it to Him.
