A Day in the Life of Jesus
Walking with Jesus through the Gospels always challenges me to re-examine what I think I know about faith, discipleship, and daily obedience. Today’s passage in Luke 17:5–10 captures a moment when the apostles came to Jesus with a sincere request: “We need more faith; tell us how to get it.” I imagine their tone—earnest, perhaps even a little desperate. They had just heard Jesus teaching about forgiveness, a calling so radical it must have felt impossible to them. In response, they asked for more of what they believed they lacked: more faith.
Jesus’ reply, however, doesn’t fit into their request neatly. Instead of explaining how to “increase” faith, He tells them that faith the size of a mustard seed could uproot a mulberry tree and cast it into the sea. His words remind me that the question is not about the quantity of faith but about its quality and genuineness. A seed may be small, but if it is alive, it will grow. And when genuine faith takes root, no matter how tiny it may seem at the start, it sets into motion a process of transformation that eventually becomes impossible to ignore.
The Mustard Seed Principle
A mustard seed is famously small, yet packed with life. In another teaching, Jesus compared the kingdom of God to a mustard seed, which starts almost invisible but grows into a tree large enough for birds to nest in its branches (Matthew 13:31–32). The disciples were focused on the size of their faith, but Jesus redirected them to its substance.
Faith is not a tool to wield for our own ends, nor a performance to impress others. It is, at its core, complete dependence on God and willingness to obey Him. As the commentator Matthew Henry once wrote, “Faith is the root, and obedience the fruit.” The two cannot be separated. If we trust God even in the smallest measure, that seed of faith will grow into acts of obedience that reflect our reliance upon Him.
And so, Jesus’ response reframes the question: it’s not about getting “more” faith, but about nurturing and acting upon the faith you already have. This faith, like a seed, spreads beneath the surface where no one can see, then gradually pushes upward, transforming the landscape of your life.
Faith and the Servant’s Duty
Jesus follows His mustard seed teaching with an illustration about a servant returning from the fields. After plowing or tending sheep, the servant doesn’t sit down expecting to be praised. Instead, he first serves his master’s meal before taking care of himself. And when he has done all that was required, he does not expect thanks, for he has merely done his duty.
This parable might sound harsh at first. Does obedience mean God doesn’t care about us or doesn’t reward us? Of course not. Elsewhere in Scripture, we see the Father’s delight in blessing His children and the Son’s promise of reward for faithful service (Matthew 25:21). What Jesus is warning against here is not service itself but spiritual pride. The danger comes when we confuse obedience with merit, or when we see our faithful service as a bargaining chip to demand God’s favor.
In truth, obedience is the natural outflow of faith. If faith is alive, it grows into obedience. But this obedience is not “extra credit” to boast about; it is simply the duty of one who has been redeemed. The joy comes not from recognition but from the privilege of serving the Lord who has already given us everything. As Dietrich Bonhoeffer wrote in The Cost of Discipleship, “Faith is only real when there is obedience, never without it, and faith only becomes faith in the act of obedience.”
Living Seed Faith Today
When I reflect on this passage, I see myself in the disciples’ plea. How often do I say, “Lord, I need more faith,” when what I truly need is the courage to act upon the faith I already have? Jesus isn’t asking me to perform great feats of belief, but to let the living seed of trust in Him take root and grow.
Perhaps your faith feels small today, like a seed in your hand. Don’t despise that smallness. Remember that the same God who created the universe delights in nurturing seeds—both in the soil and in the soul. If that tiny seed is genuine, it will grow. Slowly, quietly, and sometimes imperceptibly, it will begin to change you from the inside out. It will uproot bitterness, destroy pride, and dislodge competing loyalties that seek to take God’s place in your life.
Our calling, then, is to tend the seed through obedience. Forgiving when it feels impossible. Trusting when the outcome seems uncertain. Serving when no one applauds. Each act of obedience is not a performance but a reflection of genuine faith. And as these small acts accumulate, they bear witness to the living God at work within us.
A Pastoral Reflection
I find it freeing to remember that Jesus never called me to “grow more faith” on my own. Faith, like a seed, grows because of God’s design and God’s nurture. My responsibility is to plant it through trust and water it through obedience. The rest is in His hands.
Paul reminds us in 1 Corinthians 3:7, “So neither the one who plants nor the one who waters is anything, but only God, who makes things grow.” Faith is never about my performance or ability but about God’s power to bring life from the smallest beginnings. That truth keeps me humble and hopeful.
So today, instead of asking God for “more” faith as though it were a commodity, I ask Him to help me live faithfully with the measure I already have. I ask Him to deepen my trust in His promises and to shape me into a servant who delights in obedience—not because it earns me favor but because it reflects the life of Christ within me.
May the Lord bless you today with the assurance that even seed-sized faith is enough when placed in His hands. May you walk in obedience, not out of pride or duty alone, but out of joy in serving the One who has already given you eternal life. And may the small seed of faith within you grow into a living testimony of God’s power, uprooting every obstacle and producing fruit that glorifies His name.
