It is no strain of metaphor to say that the love of God and the wrath of God are the same thing, described from opposite points of view. How we shall experience it depends upon the way we shall come up against it: God does not change; it is man's moral state that changes. The wrath of God is a figure of speech to denote God's unchanging opposition to sin; it is His righteous love operating to destroy evil. It is not evil that will have the last word, but good; not sorrow, but joy; not hate, but love.
