What’s an evangelical? British historian David Bebbington identifies these four key points:
1. Emphasis on being born again
2. Emphasis on the ultimate authority of the Bible
3. Involvement in sharing the faith
4. Focus on the atoning and redeeming work of Christ on the cross.
But consider this: among folks who are outsiders to the Christian faith, the number that had a good impression of the word evangelicals was 3%. Not so impressive.
