What does Luke 7:22 mean?

He told them, 'Go back and tell John what you've seen and heard: people who were blind can see, those who couldn't walk are walking, people with skin diseases are healed, those who couldn't hear can hear, the dead are raised, and the poor are hearing good news.' Luke 7:22 - Modern Text Bible

(Jesus points to his actions as proof—he's fulfilling the signs expected of the Messiah, especially caring for the most vulnerable.)
