All of the 2,000+ "prophecies" being fulfilled were said to be fulfilled in THE BIBLE itself, and mostly in the New Testament. Using internal scripture does not show any evidence. Saying "X will happen and it shall be so" in the old testament, and then saying "X happened like so" in the new testament, is unconvincing to say the least. There is no evidence of it happening in the first place.
It amazes me how so many preachers of it refuse to see that anything written in that book is nothing but stories, not solid facts. And if they think it's facts simply because The Lord stated them then maybe they should provide proof of the Lord's actual testament, not something OTHERS wrote for Him.
I'm not saying all the stories are fact, but there are a lot that are backed up by actual historical evidence. Sennacherib's Annals prism is just one example and just remember that antiquarian history was written to favour the people it was written for ... so there will be discrepancies
