”˜This is not just a “theological formula”. If we left it out, we would have a Word of God that is separated from God; we would make God the prisoner of our thoughts or theologies. We would have a Word with which we could operate, a Word we could “use”, a Word we could judge. But it could not be the Word of God, the Word which operates with us, uses us, and judges us. Our work in the Church, therefore, can only be a service to this one life-giving Word of God. The clearest expression of this truth is the fact that there is no other way to preach than to preach an “expository sermon”, and even this is not a guarantee’.
