When we speak of the wrath of God, we imagine that God is irrationally full of rage, ready to “make heads roll” because he is so livid. In the same way that God’s love is not a silly, sappy feeling but rather a consistent desire for the good of his people, so also the wrath of God is not a crazed rage but rather a consistent opposition to sin and evil. God hates sin, we say (not the sinner, however), but even then, the idea of God hating something seems beneath him. We have a difficult time with the concept of God’s wrath and judgment and condemnation because our only examples of these things are so negative.
The solution to the problem is in understanding that in the Bible the wrath of God is pathos and not passion. The Anchor Bible Dictionary explains the difference:
the wrath of Yahweh is portrayed somewhat differently from human anger in the Hebrew Bible. In some respects this is essentially the difference between “passion” and “pathos.” Passion can be understood as an emotional convulsion…and…a loss of self-control…. “Pathos” on the other hand, is an act formed with care and intention, the result of determination and decision.
The wrath of God is not like human wrath, which is a reckless and irrational passion. God’s wrath is mindful, objective, rational response. It is actually an act of love.
Wrath is a necessary reaction of a loving and holy God, a good and beautiful God, to evil. God’s wrath is a temporary and just verdict on sin and evil.
