Dr. Craig is a liar.

[SteveII]

Why do you think God needs to "think" about anything prior to creation? 
Why can't causation be simultaneous with its effect? Why does causation presuppose the existence of time? 
Why can't God become temporal the moment there was something to have a temporal relationship with?

You misunderstood the sentence: "The image of God existing idly before creation is just that: a figment of the imagination." The point was NOT to imagine God sitting idly.

Aaaand...god-magic.   [emoji53].   Steve:  TT is not required to think any of these things about God.  He can simply follow logic and reason where they lead.  You're the one making the assertions (e.g. God has some other magical way of coming up with the idea of creation without using "thoughts" or "a mind," which frankly, is idiotic and desperate when you consider it from an unbiased POV), so if you expect anyone to take them seriously you must support them with evidence.

Wait a minute. Aren't you the one that just claimed that logic and reason are constructs of humans and limited to our universe? How do these then apply to discussing God prior to the universe? 

I am not making assertions. I am defending the inferences made by the KCA.
