Gospel Definitions: A.B. Luter, Jr.
The Greek word euangelion, frequently translated “gospel,” means “glad tidings,” or “good news,” and in Pauline usage it refers to the message of God’s saving work in Jesus Christ. Of the seventy-six instances of “gospel” in the NT, sixty are found in the Pauline corpus… Euangelion is for Paul the classic expression of the grace of God, responded to by faith.
