Failed prophecy

Does anyone remember how TF responds to the fact that all of Berg's prophecies have failed? I know I've read it somewhere, but am having trouble remembering where. If I remember correctly, they say something like his prophecies were contingent on certain factors. Oh ya, as I'm writing this I recall something after Ricky's death, where they responded to the fact that Berg had prophesied that Ricky was one of the two witnesses in Revelations 11. If I find it I'll post it here.
