We know that God is as loving as he is just. He is not more loving than he is just, nor more just than he is loving. All of his attributes are perfectly balanced.
Evangelical Christians have therefore always accepted the truth that God's holiness and justice sometimes requires a response of wrath. Hopefully, this is not something we cherish, but rather we accept as a necessary part of his justice.
However, I find myself wondering if we have misunderstood part of the biblical doctrine of God's wrath, and it can be summarized with this question. What is on God's face when he is meting out punishment — a scowl or a smile, or tears?
