Craig's Holy Spirit Epistemology

I'm not a defender of Craig's epistemology. I'm against using Craig's Holy Spirit Epistemology against him when he's presenting an unrelated argument. But, if if he had a sufficiently direct experience of God at some time t1, he can't guarantee that he will have that same experience if he were to come to think his theistic arguments have been refuted at time t2. So I don't see how he can say how he would react if he were to discover that his arguments were bad.
