Spiritual Terrorists Pose The Most Threat

“It is also quite clear form the biblical record that spiritual terrorists and saboteurs within the church pose a far more serious threat than manifestly hostile forces on the outside. From the very start of the church age, all the most spiritually deadly onslaughts against the gospel have come from people who pretend to be Christians – not from atheists and agnostics on the outside.”

(John MacArthur, “The Truth War”, pg. 82-83)
