The conclusion thus far is that God's wrath is to be understood neither as purely impersonal nor in crudely anthropomorphic terms. So to what does "the wrath of God" refer? It is God's personal, vigorous opposition both to evil and to evil people. This is a steady, unrelenting antagonism that arises from God's very nature, his holiness. It is God's revulsion to evil and all that opposes him, his displeasure at it and the venting of that displeasure. It is his passionate resistance to every will that is set against him.
These "definitions" raise an issue that is often ignored. What is the object of God's wrath? Is God angry with evil or with evil people? In the New Testament both are true. Often God's wrath is referred to without precisely specifying the object of that wrath (e.g., Matt. 3:7; Luke 3:7; Rom. 4:15; Rev. 14:19; 15:1, 7). In one place the object of God's wrath is evil (Rom. 1:18), although even here the perpetrators are mentioned. Where an object is mentioned it is usually evildoers (e.g., Luke 21:23; John 3:36; Rom. 2:5, 8; Eph. 5:6; Col. 3:6; 1 Thess. 2:16). Thus a comprehensive verdict would be to say that God's wrath is directed primarily against evildoers because of the evil that they do.
Where does this leave the modern cliché that "God hates the sin but loves the sinner"? Like most clichés it is a half-truth. There are two ways in which it could be taken. The first, which is undoubtedly the way that most people take it in the modern liberal West, is as a comment about the wrath of God. God's displeasure is against sin but not against the sinner. Apart from the fact that this reverses the emphasis of the New Testament, there are problems with it. As William Temple observes, "that is a shallow psychology which regards the sin as something merely separate from the sinner, which he can lay aside like a suit of clothes. My sin is the wrong direction of my will; and my will is just myself as far as I am active. If God hates the sin, what He hates is not an accretion attached to my real self; it is myself, as that self now exists." It is incoherent to say that God is displeased with child molestation but feels no displeasure toward child molesters. In what sense, then, is the cliché true? It is to be understood not as limiting the objects of God's displeasure to sinful actions but as affirming God's grace. God loves sinners, not in the sense that he does not hate them along with their sin, but in the sense that he seeks their salvation in Christ. While his attitude to sinners as sinners is antagonism and wrath, his good will toward them actively seeks their conversion and forgiveness.
