Do you believe that finding David's Palace necessarily means that the Biblical narrative of King David is historically accurate?
Actually, that is a fair question. I think if they do confirm that they HAVE found David's Palace, then it does lend weight to the narrative of King David being historically accurate. However, I would not say that they should stop there. Because simply finding the Palace does not logically make it NECESSARY that the narrative is accurate, it simply suggests that it may be.
I think that they need to continue to do as much work on Biblical archeology as can possibly be done. Its kind of like a jigsaw puzzle to me. The more pieces that you fit in, the more you find out, but the more you want to get the thing finished to have the complete picture. Just finding David's Palace will be great, of course. It will tell us a great deal. But it won't ultimately tell us if the entire narrative is correct. It will tell us that some of it is.
Why you do believe that the Bible is historically accurate? This seems like a reasonable question.
This is also a good question, and a fair one. First, let me say that I am sticking with the Hebrew Bible for this question, ie, the "Old Testament". The so-called "New Testament", the Christian Scriptures, are outside my purview.
Why do I believe it to be historically accurate? Well, a lot of it is. I mean, they have done a lot of research and proven that the post-Exilic stuff IS accurate. As far as the pre-Exilic stuff, I don't deny that more research is still needed. And its being done. And just as at one time, there was NO proof of King David, and yet now there is some, more and more, different things in the Bible are popping up on the ground. Now, does that mean that the whole thing has been proved from Genesis to Chronicles (using the Jewish order of Books)? No.
But more and more, we are beginning to see evidence of the Hebrews sojourn in Egypt (I speak of that earlier in this thread, where they have archaeological evidence of bricks being made with cut straw, torn straw, and pure mud), and other evidences.
Now, ultimately, do I believe the Bible will be vindicated? Yes, I do. At present, I rely on Faith. But I think that one day, all this will be borne out in the historic record. It will take some time though, because archeology is NOT at all an exact science.
