Be sure to read this and this.
Here’s a sample:
The biblical doctrine of God’s wrath is rooted in the doctrine of God as the good, wise and loving creator, who hates – yes, hates, and hates implacably – anything that spoils, defaces, distorts or damages his beautiful creation, and in particular anything that does that to his image-bearing creatures. If God does not hate racial prejudice, he is neither good nor loving. If God is not wrathful at child abuse, he is neither good nor loving. If God is not utterly determined to root out from his creation, in an act of proper wrath and judgment, the arrogance that allows people to exploit, bomb, bully and enslave one another, he is neither loving, nor good, nor wise. To trivialize – almost to domesticate! – this massive biblical doctrine, rooted as it is in the doctrines of God as creator and as the one who will restore his creation at the last (in other words, in the biblical sense, ‘judge’), into a few anecdotal trivialities about God petulantly hurling thunderbolts around is hardly the way to begin a serious argument.
And to go ahead and cover my bases, I am really really really for penal substitution. To quote Johhny Cash and the Blind Boys of Alabama, “Sooner or later God’s gonna cut ya down.”
