“The idea of ‘good news,’ for which an older English word is ‘gospel,’ had two principal meanings for first-century Jews. First, with roots in Isaiah, it mean the news of YHWH’s long-awaited victory over evil and rescue of his people. Second, it was used in the Roman world of the accession, or birthday, of the emperor. Since for Jesus and Paul the announcement of God’s inbreaking kingdom was both the fulfillment of prophecy and a challenge to the world’s present rulers, ‘gospel’ became an important shorthand for both the message of Jesus himself, and the apostolic message about him. Paul saw this message as itself the vehicle of God’s saving power (Romans 1:16, 1 Thessalonians 2:13).
