Here’s the clincher of what Craig wrote, and quite frankly why he wrote it (from the link I put up above):

[…]

Moreover, my point above returns. Nothing could so illustrate to the Israelis the seriousness of their calling as a people set apart for God alone. Yahweh is not to be trifled with. He means business, and if Israel apostasizes the same could happen to her. As C. S. Lewis puts it, “Aslan is not a tame lion.”

Now how does all this relate to Islamic jihad? Islam sees violence as a means of propagating the Muslim faith. Islam divides the world into two camps: the dar al-Islam (House of Submission) and the dar al-harb (House of War). The former are those lands which have been brought into submission to Islam; the latter are those nations which have not yet been brought into submission. This is how Islam actually views the world!

By contrast, the conquest of Canaan represented God’s just judgement upon those peoples. The purpose was not at all to get them to convert to Judaism! War was not being used as an instrument of propagating the Jewish faith. Moreover, the slaughter of the Canaanites represented an unusual historical circumstance, not a regular means of behavior.

The problem with Islam, then, is not that it has got the wrong moral theory; it’s that it has got the wrong God. […]

So Craig, in doing his best to sell more of his books to the American religious right, finally delivers the punch line: Our God is bigger/better then their god.
