Faith for the Valley Below
Month 9: The Road to Jerusalem · Walking in the Spirit
Today's Scripture
Read together: Matthew 17:14-20
14 When they came to the crowd, a man came up to Jesus and knelt before Him. 15 “Lord, have mercy on my son,” he said. “He has seizures and is suffering terribly. He often falls into the fire or into the water. 16 I brought him to Your disciples, but they could not heal him.” 17 “O unbelieving and perverse generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy here to Me.” 18 Then Jesus rebuked the demon, and it came out of the boy, and he was healed from that moment. 19 Afterward the disciples came to Jesus privately and asked, “Why couldn’t we drive it out?” 20 “Because you have so little faith,” He answered. “For truly I tell you, if you have faith the size of a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”

Today's reading: Ezekiel 17-19
Reading the whole Bible in a year — do this when you have extra time. (Around Day 252 of 365 — riddles and laments over Israel's fallen leaders.)The Heart of It
At the foot of the mountain, right after all that glory, Jesus and the three disciples walk into a mess. A desperate father runs up, kneels, and begs, "Lord, have mercy on my son… I brought him to Your disciples, but they could not cure him" (). The other nine disciples had tried to help and failed. There's a crowd, an argument, an embarrassed group of followers, and a boy still suffering. This is what the valley below the mountaintop often looks like. There is real need, real struggle, and the painful discovery that our own strength isn't enough. Jesus heals the boy immediately. But then the disciples pull Him aside with the honest question we all eventually ask: "Why could we not cast it out?" ().
Jesus' answer goes to the heart of walking in the Spirit: "Because of your unbelief" (). Then He adds the famous picture. Faith like a tiny mustard seed can move mountains. Here is the key for our family. Spiritual power doesn't come from us working ourselves up. It comes from real trust in God, who supplies the power. The disciples had real authority from Jesus. But somewhere their dependence had drifted into routine. They were leaning on past success or their own technique instead of leaning, fresh and humble, on God. Walking in the Spirit is exactly this. It is not striving in our own willpower. It is trusting the living God and depending on Him in the moment. And notice what Jesus says. It isn't the size of our faith that matters but its object. Even mustard-seed faith does great things, because it's connected to a great God. We don't need huge faith. We need real faith in a huge Savior, fresh today. The same Jesus who shone on the mountain is the One who meets us, full of power, in the valley.
Around the Table
Jesus' helpers tried to make a sick boy well, but they couldn't. So they brought him to Jesus, and Jesus made him all better right away! When we can't, Jesus can.
Let's do it: Hold up your tiniest finger and say, "Even small faith in a big God is enough! Jesus, I trust You!"
Jesus said faith as small as a mustard seed can do amazing things. And a mustard seed is teeny! Why isn't it about having huge faith?
Let's talk: The disciples were trying in their own strength and failed. What's the difference between trying hard on our own and trusting God to give the power?
Real spiritual power flows from dependence on God, not from our own technique or hype. Jesus connects the disciples' failure to drifting from genuine trust. Faith's strength is in its object, a great God, not in its size.
Let's go deeper: Where are you tempted to handle life in your own willpower instead of depending on the Holy Spirit? What would mustard-seed trust look like there this week?
💬 Conversation Starter
Can you think of a time you tried really hard at something and still couldn't do it, until you got help?— Walking in the Spirit means trusting God's power instead of just our own muscle.
🛡️ Defending the Faith
Some say miracles like this just don't happen. But the eyewitness Gospels report Jesus healing this boy plainly and publicly, before a crowd that had just watched the disciples fail. That is exactly the kind of embarrassing detail invented stories leave out. The God who made nature can act within it, and we share that confidently and kindly ().
For Dad · Go Deeper
This passage is a gift for a Spirit-filled home because it guards two ditches at once. On one side is powerless religion. That is the disciples going through the motions of ministry with no living dependence on God, surprised to find nothing happens. On the other side is self-made spirituality. That is the temptation to think power comes from our intensity, our formula, or our reputation. Jesus cuts between both. The issue was "unbelief," a drift from fresh, humble trust in the Father. Notice how anti-hype Jesus is. He doesn't tell them to try harder, shout louder, or work up more emotion. He points them to the size of their God, not the size of their feelings. Mustard-seed faith moves mountains because it's tethered to the Almighty. For you as a dad, the application is searching. Ministry to your own children can quietly become technique. The right routines, the right verses, the right discipline, all running on yesterday's grace rather than today's dependence. The cure isn't more striving. It's returning, daily and empty-handed, to trust the God who actually does the work. To walk in the Spirit means just that: walk with Him, lean on Him, draw from Him. Lead your family to expect God to act. Not because we've worked ourselves up, but because He is great, present, and good.

Let's Pray Together
"Father, forgive us for trying to live in our own strength. Teach our family to lean on You every day. Grow real faith in us, even faith as small as a seed. We trust in You, our great God. And let Your Spirit work through us today. In Jesus' name, amen."
I don't need huge faith. I need real faith in a huge God, leaning on His Spirit fresh today.
