Quick answer

Jesus asks, 'Don't you understand yet?' His question exposes their lingering spiritual blindness.

Overview

The unanswered question leaves the disciples—and the reader—to reckon with how slow they are to perceive Jesus' identity and power. It immediately precedes the two-stage healing of a blind man, which mirrors their partial sight. Mark uses this to show that true understanding of Jesus comes gradually and only by his gracious work.

Christ at the center

Mark drives urgently to the cross, showing Jesus the Son of God as the suffering Servant who 'came not to be served but to serve, and to give his life as a ransom for many.'
