I think you need to listen to the podcast, I think it was the last one or one before that, he specifically stated god had no attributes that were either actually infinite or potentially infinite.
But if we use the strict defintion we have it means "not Finite" never ending
yet WLC has problems with infinite when attributed to the universe or things in it. Suddenly infinity isnt absurd when god is involved.
Or in other words you can go on smiling for ever and yet you will find that you have never smiled an infinite number of times.
did you not listen to WLC podcast? he denied actual and potential infinites.
By the way, I disagree with Dr. Craig about time and eternity because I'm a Thomist who believes in divine timelessness.
