Quick answer

The father says he begged the disciples to cast it out, but they could not. Their failure exposes the limits of power apart from faith and dependence on Christ.

Overview

The disciples, who had earlier been given authority, are now unable to help, revealing a weakness in their faith. Their failure sets the stage for Jesus to act where they could not. It teaches that spiritual power flows not from method but from genuine faith in and reliance upon the Lord.

Christ at the center

Luke shows Jesus the Savior for all — outsiders, the poor, the nations — the one who, on the Emmaus road, opened all the Scriptures to show they were about himself.

How Luke 9:40 points to him is part of the one story that runs through all Scripture — meet Jesus at the heart of the web, or follow a trail that traces him from Genesis to Revelation.
