I Believe, Help Me Overcome My Unbelief
The disciples’ failure to heal exposes the danger of trusting in themselves, while Jesus shows that even half-hearted belief, when joined to him, is enough to raise the dead.
9:14 When they came to the other disciples, they saw a large crowd around them and the teachers of the law arguing with them. 15 As soon as all the people saw Jesus, they were overwhelmed with wonder and ran to greet him.
16 “What are you arguing with them about?” he asked.
17 A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech. 18 Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not.”
Back down from the dazzling mountaintop, the disciples find themselves in the mud of ordinary life again—argument, failure, and chaos. While Jesus, Peter, James, and John were basking in glory, the other nine had been floundering. A man had brought his demon-possessed son for healing, and the disciples couldn’t help. It’s almost comic if it weren’t so tragic: the ones who once cast out demons with nothing but Jesus’ word are now empty-handed, bickering with the teachers of the law while a father watches his son writhe in torment. They had begun this journey as nobodies with no résumé, no pedigree, and no illusions of strength—perfect soil for grace to grow. But now, with success under their belts, stories to boast of, and reputations on the rise, they stumble over their own importance. From miracle workers back to incompetents in the span of a few chapters. And here stands a desperate father, looking for hope, staring at the wreckage of their failure.
19 “You unbelieving generation,” Jesus replied, “how long shall I stay with you? How long shall I put up with you? Bring the boy to me.”
20 So they brought him. When the spirit saw Jesus, it immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth.
21 Jesus asked the boy’s father, “How long has he been like this?”
“From childhood,” he answered. 22 “It has often thrown him into fire or water to kill him. But if you can do anything, take pity on us and help us.”
23 “‘If you can’?” said Jesus. “Everything is possible for one who believes.”
24 Immediately the boy’s father exclaimed, “I do believe; help me overcome my unbelief!”
Jesus’ response isn’t exactly warm and fuzzy: “You unbelieving generation, how long shall I stay with you? How long shall I put up with you?” It must have stung. But don’t miss the grace hidden in the jab. His exasperation isn’t the end of the story—it’s the doorway back into dependence. “Bring the boy to me.” And the boy is brought, convulsing, foaming, chained by a spirit that had owned him since childhood. The father’s plea is almost painful in its honesty: “If you can do anything, take pity on us and help us.” If. That single syllable hangs in the air, exposing both the father’s weariness and the disciples’ failure. Jesus repeats it back with a sharp edge—“If I can?”—before answering with one of the most hope-laden statements in all of Scripture: “Everything is possible for one who believes.” But here’s the kicker: the only one who actually believes, with full and flawless faith, is Jesus himself. The rest of us stumble along with half-faiths, mustard-seed trusts, and shaky prayers. The father’s desperate cry is ours too: “I do believe; help me overcome my unbelief!”
25 When Jesus saw that a crowd was running to the scene, he rebuked the impure spirit. “You deaf and mute spirit,” he said, “I command you, come out of him and never enter him again.”
26 The spirit shrieked, convulsed him violently and came out. The boy looked so much like a corpse that many said, “He’s dead.” 27 But Jesus took him by the hand and lifted him to his feet, and he stood up.
Then Jesus does what he came to do. He commands the spirit to leave. The boy collapses like a corpse, lifeless on the ground. It looks like death has won—until Jesus kneels, takes the boy’s hand, and raises him up. A glimpse of resurrection. A foreshadowing of what’s coming when Jesus himself will go all the way down into death, only to rise again and drag the whole broken world with him. That day, one boy went from death to life, and everyone watching saw a glimpse of the kingdom that is stronger than every demon, every failure, every grave.
28 After Jesus had gone indoors, his disciples asked him privately, “Why couldn’t we drive it out?”
29 He replied, “This kind can come out only by prayer.”
Later, in private, the disciples ask the question that must have burned in their throats: “Why couldn’t we drive it out?” And Jesus answers with a line that cuts to the heart: “This kind can come out only by prayer.” Don’t misunderstand—this wasn’t a special demon requiring a secret exorcism ritual. This was Jesus pointing out the rot setting in among his friends. They hadn’t prayed because they thought they didn’t need to. They started this story empty, clinging to nothing but grace, and through that nothing God did wonders. But somewhere along the way they started believing their own press clippings, thinking power was theirs to wield instead of a gift to receive. And when losers start to believe they’re winners, they become just like the Pharisees. The disciples’ failure wasn’t that they didn’t have enough faith—it’s that they forgot to bring the scraps of faith they have to the one who can move mountains.
Reflection Question
How might your own failures be an invitation to rediscover reliance on Jesus rather than confidence in yourself?
