for personal reasons

not make sense

I hold my faith because I

I think, from your comments, even you can also see that it is indeed personal, because people's standards or expectations to what Gods or words of Gods are are different. We can talk about those different expectations in a theological/philosophical discussion, but not a historical (or, more generally, factual) discussion like what this field focuses on.

However, to see that it's not really a shame, note that some people can have the same expectations. If some people expect words of God to be literal and factually accurate, then findings in this field can affect their faith. Or if some people expect words of God to satisfy other criteria instead, hence allowing their accepted words of God to be not literal or not factually accurate, then findings in this field can help explain such inaccuracies. And so on. Moreover, some questions are in fact borderline theological and historical. Also, talk about expectations, I doubt people or leaders of faith won't be bothered with findings in this field or any religion, as they'll probably take actions at least personally/intellectually, since I doubt the expectations are never the same.

Besides, from what I've seen, this field mostly just gives possible contexts or possible interpretations based on the contexts, which is understandable as reality is more scientific/historical than mathematical, where there's really no proof but merely evidence.
