I think no one knows the Bible more than he.
Whose Word Is It?
It is an extreme position held only by some Christian groups that the Bible – in its entirety - cover to cover is the revealed word of God in every word, but they do a clever thing when they mention this, or make this claim. They will say that the Bible in its entirety is the word of God; inerrant (no mistakes) in the original writings.
So if you go to the Bible and point out some mistakes that are in it you are going to be told: Those mistakes were not there in the original manuscript, they have crept in so that we see them there today.
They are going on problem in that position. There is a verse in the Bible Isaiah 40:8 which in fact is so well known that some Bibles printed it on the inside front cover as an introduction and it says : “ The grass weathers, the flower fades, but the word of our God stands forever”. Here is a claim in the Bible that the word of God will stand forever, it will not be corrupted, it won't be lost. So if today you find a mistake in the Bible you have two choices. Either that promise was false that when God said my word wont fade away, he was mistaken, or the portion which has the mistake in it was not a part of the word of God in the first place, because the promise was that it would be safeguarded, it would not be corrupted.
