Jesus quotes Isaiah, saying that he had been sent “to proclaim good news to the poor… proclaim liberty to the captives and recovering of sight to the blind, to set at liberty those who are oppressed.”
Like the audience in the synagogue that day, we too have been given good news, as Paul describes “the mystery of Christ… that the Gentiles are fellow heirs…partakers of the promise in Christ Jesus through the gospel.” We’ve been set free from the captivity of sin, had our eyes opened, and been offered everlasting liberty from the pain and suffering of a mortal life.
