Authority Over Demons and Power of Prayer
Faith leaning on Christ through prayer overcomes unbelief and evil.
Mark 9:14–29 (BSB)
14 When they returned to the other disciples, they saw a large crowd around them, and scribes arguing with them.
15 As soon as all the people saw Jesus, they were filled with awe and ran to greet Him.
16 “What are you disputing with them?” He asked.
17 Someone in the crowd replied, “Teacher, I brought You my son, who has a spirit that makes him mute.
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 it out, but they were unable.”
19 “O unbelieving generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy to Me.”
20 So they brought him, and seeing Jesus, the spirit 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 this been with him?” “From childhood,” he said.
22 “It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.”
23 “If You can?” echoed Jesus. “All things are possible to him who believes!”
24 Immediately the boy’s father cried out, “I do believe; help my unbelief!”
25 When Jesus saw that a crowd had come running, He rebuked the unclean spirit. “You deaf and mute spirit,” He said, “I command you to come out and never enter him again.”
26 After shrieking and convulsing him violently, the spirit came out. The boy became like a corpse, so that many said, “He is dead.”
27 But Jesus took him by the hand and helped him to his feet, and he stood up.
28 After Jesus had gone into the house, His disciples asked Him privately, “Why couldn’t we drive it out?”
29 Jesus answered, “This kind cannot come out, except by prayer.”
What is the big idea of Mark 9:14–29?
Faith leaning on Christ through prayer overcomes unbelief and evil.
How does Mark 9:14–29 point to Christ?
Jesus’ authority over evil anticipates His decisive victory at the cross, where He defeats sin and Satan, offering deliverance and new life to all who believe.
How does Mark 9:14–29 relate to the life and ministry of Jesus?
Descending from the mountain of glory, Jesus encounters a disputing crowd and scribes (γραμματεῖς, grammateis) arguing with His disciples. A man explains that he brought his son possessed by a mute spirit (πνεῦμα ἄλαλον, pneuma alalon). The spirit seizes him (καταλαμβάνει, katalambanei), throws him down, and causes convulsions. The disciples were unable (οὐκ ἴσχυσαν, ouk ischysan) to cast it out. Jesus responds, 'O unbelieving generation' (Ὦ γενεὰ ἄπιστος, Ō genea apistos), lamenting their lack of faith. The father pleads, 'If You can' (Εἴ τι δύνῃ, Ei ti dynē), and Jesus replies, 'All things are possible for the one who believes' (πάντα δυνατὰ τῷ πιστεύοντι, panta dynata tō pisteuonti). The father cries out, 'I believe; help my unbelief' (Πιστεύω· βοήθει μου τῇ ἀπιστίᾳ, Pisteuō; boēthei mou tē apistia). Jesus rebukes (ἐπετίμησεν, epetimēsen) the unclean spirit (τῷ πνεύματι τῷ ἀκαθάρτῳ, tō pneumati tō akathartō), commanding it to come out (ἔξελθε, exelthe) and never enter again. After convulsing violently, the boy appears like a corpse (ὡσεὶ νεκρός, hōsei nekros), but Jesus takes him by the hand (κρατήσας τῆς χειρός, kratēsas tēs cheiros) and raises him up (ἤγειρεν, ēgeiren). Later, Jesus explains privately that this kind can only come out by prayer (ἐν προσευχῇ, en proseuchē). The life of Christ here reveals the stark contrast between mountaintop glory and valley unbelief, the authority of Christ over demonic oppression, and the necessity of dependent faith expressed through prayer.
Authorial Intent
To demonstrate that Christ’s authority over evil is accessed through faith-dependent prayer.
Literary Context
This episode follows the Transfiguration, contrasting revealed glory with earthly struggle. It precedes the second passion prediction (9:30–32), reinforcing the disciples’ ongoing misunderstanding.
Historical Context
Exorcism was not unknown in Jewish tradition, but Jesus’ authority surpasses conventional methods. The expression 'unbelieving generation' echoes Deuteronomy 32:5. The father’s confession represents raw, imperfect faith.
Chapter: Mark 9
Glory, Unbelief, Suffering, Humility, and Radical Discipleship
The beloved Son revealed in glory must be listened to as he leads his disciples through suffering, prayerful dependence, humble service, kingdom generosity, radical holiness, and peace.
