Your Father Loves You by James Packer, Harold Shaw Publishers, 1986, page for May 3.
Why do men shy away from the thought of God as a judge? Why do they feel unworthy of him? The truth is that part of God's moral perfection is his perfection in judgment. Would a God who did not care about the difference between right and wrong be a good and admirable being? Would a God who put no distinction between the beasts of history, the Hitlers and Stalins (if we dare use names), and his own saints be morally praiseworthy and perfect? Moral indifference would be an imperfection in God, not a perfection. And not to judge the world would be to show moral indifference. The final proof that God is a perfect moral being, not indifferent to questions of right and wrong, is the fact that he has committed himself to judge the world.
It is clear that the reality of divine judgment must have a direct effect on our view of life. If we know that retributive judgment faces us at the end of the road, we shall not live as otherwise we would. But it must be emphasized that the doctrine of divine judgment, and particularly of the final judgment, is not to be thought of primarily as a bogeyman, with which to frighten men into an outward form of conventional righteousness. It has its frightening implications for godless men, it is true; but its main thrust is as a revelation of the moral character of God, and an imparting of moral significance to human life.
