I think what you point out about it being 2,000 years later is important, too, for us not to forget, as G-d has been at work in the world all that time, and while He has never changed, He has changed much in our world since that time. And while, as a Christian, I believe His Word has not changed, we also have to look at it prayerfully, in humility, not leaning on our own understanding, but asking Him always for renewed wisdom as we consider His Word alongside what He has done in the world over the past 2,000 years.
I have confidence in this:
At the Restoration of All Things, we all — Jew, Gentile... whatever — will be able to look back at the totality and see the not a single letter of His Word either failed or was errant. I am ever mindful that “we see now, as in an ancient mirror, only an obscure image.” When all of told, His Word will stand vindicated in totality.
