Jesus’ message of the Kingdom of God is the announcement by word and deed that God is acting and manifesting dynamically his redemptive will in history. God is seeking out sinners; he is inviting them to enter into the messianic blessing; he is demanding of them a favorable response to his gracious offer. God has again spoken. A new prophet has appeared, indeed one who is more than a prophet, one who bring to people the very blessings he promises.

The mission of Jesus brought not a new teaching but a new event. It brought to people an actual foretaste of the eschatological salvation. Jesus did not promise the forgiveness of sins; he bestowed it. He did not simple assure people of the future fellowship of the Kingdom; he invited them into fellowship with himself as the bearer of the Kingdom. He did not merely promise them vindication in the day of judgment; he bestowed upon them the status of a present righteousness. He not only taught an eschatological deliverance from physical evil; he went about demonstrating the redeeming power of the Kingdom, delivering people from sickness and even death.

The miracles of healing, important as they were, were not an end in themselves. They did not constitute the highest good of the messianic salvation. This fact is illustrated by the arrangement of the phrases in Matthew 11:4-5. Greater than deliverance of the blind and the lame, the lepers and the deaf, even than raising of the dead, was the preaching of the good news to the poor. This “gospel” was the very presence of Jesus himself, and the joy and fellowship that he brought to the poor.
