Passage
And he said to them, `This kind is able to come forth with nothing except with prayer and fasting.'
And he said to them, `This kind is able to come forth with nothing except with prayer and fasting.'
Mark 9:27 but Jesus, having taken him by the hand, lifted him up, and he arose.
Mark 9:28 And he having come into the house, his disciples were questioning him by himself--`Why were we not able to cast it forth?'
Mark 9:29 And he said to them, `This kind is able to come forth with nothing except with prayer and fasting.'
Mark 9:30 And having gone forth thence, they were passing through Galilee, and he did not wish that any may know,
Mark 9:31 for he was teaching his disciples, and he said to them, `The Son of Man is being delivered to the hands of men, and they shall kill him, and having been killed the third day he shall rise,'
The verse centers on "said", "kind", "able", "come", "forth", "nothing", "except", and "prayer". It is saying that the verse draws attention to "said" and "kind", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "And he having come into the house..." into verse 30's "And having gone forth thence they were...", so "said" and "kind" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "said" and "kind" with trust shaped by these words, not by a vague optimism outside the passage.
