Looking back over the paragraph we are studying, it is important to note the paradox constituted by the first and last statements. On the one hand, God was in Christ reconciling. On the other, God made Christ to be sin for us. How God can have been in Christ when he made him to be sin is the ultimate mystery of the atonement. But we must hold both affirmations tenaciously, and never expound either in such a way as to contradict the other.
