The word gospel derives from the Old English gōd-spell (rarely godspel), meaning "good news" or "glad tidings". The word comes from the Greek euangelion, or "good news". The gospel was considered the "good news" of the coming Kingdom of Messiah, and of redemption through the life and death of Jesus, the central Christian message.
