I read an interesting article in Themelios. You can access it here. The article you are looking for is pages 4-6 and is written by Carl Trueman, entitled, ‘Know Your Limits: The Key Secrets Of Theological Controversy.’
He makes some interesting points, particularly concerning those of us who waste many hours dealing with theological ‘controversies’ (a la Rob Bell) which actually have no direct relation to our daily lives and ministries. Read it and see what you think.
