Passage
And when he was entered into the house, his disciples asked him privately, Wherefore could not *we* cast him out?
And when he was entered into the house, his disciples asked him privately, Wherefore could not *we* cast him out?
Mark 9:26 And having cried out and torn [him] much, he came out; and he became as if dead, so that the most said, He is dead.
Mark 9:27 But Jesus, having taken hold of him by the hand, lifted him up, and he arose.
Mark 9:28 And when he was entered into the house, his disciples asked him privately, Wherefore could not *we* cast him out?
Mark 9:29 And he said to them, This kind can go out by nothing but by prayer and fasting.
Mark 9:30 And going forth from thence they went through Galilee; and he would not that any one knew it;
The verse centers on "entered", "house", "disciples", "asked", "privately", "wherefore", and "cast". It is saying that the verse draws attention to "entered" and "house", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 27's "But Jesus having taken hold of him..." into verse 29's "And he said to them This kind...", so "entered" and "house" 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 "entered" and "house" with trust shaped by these words, not by a vague optimism outside the passage.
