The issue is not primarily about when and if a Christian may ever use force in self-defense, or the defense of one’s family or friends. There are significant situational ambiguities in the answer to that question. The issue is about the whole tenor and focus and demeanor and heart-attitude of the Christian life. Does it accord with the New Testament to encourage the attitude that says, “I have the power to kill you in my pocket, so don’t mess with me”?
"... when Piper extended his embrace to Mark Driscoll, all that gravitas and bona fides was added to Driscoll's resume."
