That's an article of faith, not the result of study. In my case, I made a study and was honest with the facts.
Take the predicted destruction of Tyre as only one example (and I've read the lame apologetic excuses for it, and they're completely invalid). You can't even say, "Oh, it's a prophecy, so it might still happen someday in the future," - because the Bible specifically stated *who* was going do it, *and* then admitted in its own text that that person did not do it. Which of course proves that the prophecy did in fact fail.
On the other hand, if that's too terrifying for you, I could spend years explaining it rationally, and you would be unwilling to admit even the possibility such a thing could ever be. So the real burden for examining such things - instead of blandly saying, "I'm sure some apologeticist *somewhere* has devised a really clever way around this somehow anyway," is really ultimately on you.
But if you want, as a possible example, Dems to look into say the Hillary closet, you have to be fair and be willing to be fearless about similar things yourself. Just sayin'.
