I just mean that the significance of the history is revealed in the theological truth claims associated with it. The reason we care about the history of Abraham is because of the theological importance of the covenant, and of the establishment of Israel as God’s chosen people, and of the promised Messiah. The fact that the actual historical events objectively happened in exactly the way described is less essential than what the storyline reveals about God’s interaction in our world. That doesn’t mean that I don’t care whether or not it is a “true” story. Obviously for something to count as history it has to have some relationship to a reality that actually happened. But I don’t see the OT narratives as a bare recounting of historical facts. There is a theological agenda to their telling and it doesn’t bother me if something I would consider a facet of “historical accuracy” gets sacrificed or manipulated to serve the theological agenda.
Yes, I think the Bible is true history as well, and the history is what reveals God’s character and will. To clarify better, I meant that I don’t think the significance of the history it reveals is summed up in mere facts. It is the whole storyline and trajectory that matters, and the meaning God gives to the facts and events that matter, not the bare factuality of the facts .
I think people get hung up on treating the Bible like a document to be fact-checked. I think that is a reductive approach to God’s revelation. The Bible’s authority rests on an a priori acceptance that it is the the true revelation of a God whose person is Truth, not on it’s ability to pass some kind of test we subject it to where we decide how well it holds up against what we have already decided is objectively true. I think a lot of Evangelicals want to establish the Bible’s credibility by historically (and sometimes scientifically) fact-checking it, and if it passes the test, we are authorized to believe what it says about God. I think this is backwards. We encounter God. His Spirit testifies to our hearts that his word is truth. The authority of Scripture derives from the Person who inspired it and uses it in our own lives and contexts, it’s authority is not something we ascribe to it when we have determined it is factual enough to meet our standards of truth-telling.
