Found about seventy-five times in the New Testament and occurring only once in the book of Revelation (14:6), the Greek noun “euangelion” meant “good news” or “gospel.”
Prior to the New Testament period, this noun described a good report or victorious news from a battlefield.
The “good news” involves a “kingdom” (Mt. 4:23). Some need to “repent” before they are ready to hear the gospel (Mk. 1:15). God’s good news is worth what we value most (Mk. 10:29) and is to be taken to each person in the world (Mk. 16:16). Christians should never be “ashamed” of the gospel because it is God’s power to salvation (Rom. 1:16). Those who want to be right must “obey” the gospel (Rom. 10:16) or face God’s wrath (2 Thess. 2:8). God “begets” people through His gospel (1 Cor. 4:15). Those who preach the gospel are worthy of support (1 Cor. 9:14). Some try to “pervert” the gospel of Christ (Gal. 1:7).
