Karl Barth, Epistle to the Romans, 516–17. Bold is mine; caps are Barth’s.
We are exhorted in the Epistle to the Romans to a particular line of conduct, not in order that we may adopt the point of view of God, but that we might bear it in mind, consider it from all sides, and then live within its gravity. To judge involves the capacity to assign guilt and to envelop an action in wrath. God has this capacity and exercises it continuously. But, as the capacity of God, it is invisibly one with His forgiveness and with the manifestation of His righteousness. Our action in judging possesses, however, nothing of this double-sidedness. We do not possess the divine freedom of rejecting AND electing. When we permit ourselves to judge others, we are caught up in condemnation: the result is that we merely succeed in erecting the wrath of God as an idol. . . . When God rejects and hardens there is hope and promise. . . . How different it is when men, putting themselves in God’s place, put stumblingblocks in the way of other men. They seek only to harden, and not to liberate; only to bind, and not to loose; only to kill, and not to make alive. . . . Here once again the supreme right is the supreme wrong, if we suppose that right is OUR right.
