Commentary

KJV Study Commentary
When Jesus 'was come into the house, his disciples asked him privately, Why could not we cast him out?' (εἰσελθόντος αὐτοῦ εἰς οἶκον οἱ μαθηταὶ αὐτοῦ κατ' ἰδίαν ἐπηρώτων αὐτόν, Ὅτι ἡμεῖς οὐκ ἠδυνήθημεν ἐκβαλεῖν αὐτό;). Their private question reveals humility—acknowledging failure and seeking understanding. The phrase 'why could not we' (hoti hēmeis ouk ēdynēthēmen, ὅτι ἡμεῖς οὐκ ἠδυνήθημεν) expresses genuine perplexity. They had successfully cast out demons before (Mark 6:13), so this failure was unexpected. Jesus' answer (v. 29) reveals that spiritual authority requires ongoing prayer and fasting, not just initial commissioning. Ministerial power isn't automatic or permanent but requires continuous dependence on God. The disciples' question models proper response to spiritual failure—private, humble inquiry seeking Jesus' instruction.

Historical & Cultural Context

The disciples' earlier successful exorcisms (Mark 6:7-13) during their mission made this failure surprising. Jewish exorcism practices existed, but Jesus had given disciples unique authority over demons (Mark 3:15; 6:7). Their question 'Why could not we?' assumes they should have succeeded based on previous experience. Jesus' answer about prayer and fasting introduces a crucial principle: different spiritual battles require different levels of spiritual discipline. Some victories come easily; others require intensive prayer. This became foundational for Christian spiritual warfare teaching. The early church emphasized prayer and fasting for ministry effectiveness (Acts 13:2-3; 14:23).

Reflection Questions

  1. How does the disciples' humble, private inquiry after failure model appropriate response to ministerial inadequacy?
  2. What does their surprise at failing (having succeeded before) teach about the danger of presuming upon past spiritual victories?
