Surrounding context
One of the multitude answered, “Teacher, I brought to you my son, who has a mute spirit;
and wherever it seizes him, it throws him down, and he foams at the mouth, and grinds his teeth, and wastes away. I asked your disciples to cast it out, and they weren’t able.”
He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”
They brought him to him, and when he saw him, immediately the spirit convulsed him, and he fell on the ground, wallowing and foaming at the mouth.
He asked his father, “How long has it been since this has come to him?” He said, “From childhood.
Often it has cast him both into the fire and into the water, to destroy him. But if you can do anything, have compassion on us, and help us.”
Jesus said to him, “If you can believe, all things are possible to him who believes.”

Mark, writing to an early Christian community (traditionally associated with Rome, for believers facing suffering and needing assurance of Jesus's authority), often emphasizes the failures and limitations of the disciples alongside the surpassing power of Christ. The father has already explained the situation to Jesus (verses 17-18), describing years of suffering, and now the boy himself is brought forward as living proof of the affliction's severity. The disciples had already tried and failed to cast out this spirit (v. 18), which heightens the tension and sets up Jesus's authority as the only sufficient answer.
