The answer to the problem of evil does not lie in trying to establish its point of origin, for that is simply not revealed to us. Rather, in the moment of the cross, it becomes clear that evil is utterly subverted for good.... If God can take the greatest of evils and turn them for the greatest of goods, then how much more can he take the lesser evils which litter human history, from individual tragedies to international disasters, and turn them to his good purpose as well.

Heresy is usually quite sophisticated, actually has a meaning, and is to be taken very seriously. It is therefore to be carefully distinguished from turgid, pretentious, badly-written Bullsgeshichte, to use the technical German theological term.

The theology of the cross is not a cerebral thing; it profoundly affects our Christian experience and existence, making demands upon our whole lives and turning theology into something which controls not just our thoughts, but the very way in which we experience the world around and taste the blessing and fellowship of God himself. pp.48-49

Luther’s doctrine of justification depends upon two things: the constant preaching of the wrath of God in the face of sin; and the realization that every Christian is at once righteous and a sinner, thus needing the hammer of the law to terrify and break the sinful conscience.
