For he claims that God is timeless without creation and than becomes temporal with creation. (2000, 152; 2001, 236) Why is God timeless; more importantly why did he become temporal when he created the universe? In what follows I shall deal with these questions in turn. Let me begin with the first question.
I think the answer of this question is closely connected with Craig’s concept of creation ex nihilo ; because, according to him a robust/strong doctrine of creation implies that God is the Creator of everything except Himself and the universe was created a finite time ago in the past. (2004, 161) To prove such an idea of beginning for the universe he utilizes many scientific and metaphysical arguments. Especially the cosmological argument plays a key role in his thought.
