There's no mention of Jerry Vardaman in my book on page 101, or anywhere else in that book. There was an allusion to quote "an archaeologist" that spoke of a coin in relation to the discussion on Quirinius, but no Jerry Vardaman.
On the other hand, John McRay made a number of excellent arguments that busted the skeptic's claim that a 2nd census under Quirinius was bogus. And that was the main thing I think you should take away from that.
Well, he could have gone to some of the liberal "scholars" of the Jesus Seminar, a gaggle of left-wing loons who started with an antisupernatural bias and unfounded theories, and who voted using colored beads, etc. But then you can Google refuting the Jesus Seminar to see what a sham it was that they presented.
The scholars Strobel interviewed are well known in their fields, and all have legitimate degrees, Ph.D's, etc. They present any number of excellent observations in response to specific questions posed by a skeptic of Christianity. Strobel found the information compelling, which is one of the reasons why he became a Christian.
So it's like I said, if you find anything in Strobel's book where one of the scholars interviewed presented bad information, please let me know and we'll discuss. So far you have 1 item in 101 pages? Not too shabby at all!
I think if anything, after finishing that book, you will have a much greater appreciation of the foundations of Christianity than you had before.
