God was with us, with us His enemies, with us who were visited and smitten by His wrath. God was with us in all the reality and fulness with which He does what He does. He was with us as one of us. His Word became flesh of our flesh, blood of our blood. His glory was seen here in the depths of our situation, and the full depths of our situation were disclosed for the first time when illumined then and there by the Lord’s glory, when in His Word He came down to the lowest parts of the earth (Eph 4:9), in order that there and in that way He might rob death of its power and bring life and immortality to light (2 Tim 1:10). This happened, as having happened conclusively, totally, and sufficiently. . . . This ‘God with us’ has happened. It has happened in human history and as a part of human history. Yet it has not happened as other parts of history usually happen. It does not need to be continued or completed. It does not point beyond itself or merely strive after a distant goal. It is incapable of any exegesis or even the slightest addition or subtraction. Its form cannot be changed. It has happened as a self-moved being in the stream of becoming. It has happened as completed event, fulfilled time, in the sea of the incomplete and changeable and self-changing.
