The "old testament" must become relevant and the experience of the past two thousand years must be shown to be an anomaly in Jewish history.
Does the appearance on the scene of Jesus affect that?
Who?
Wouldn't we need the benefit of observation from thousands of years in the future to determine that?
Nope. All we need to know is that the Torah is G-d's ultimate blueprint for Creation.
I assume your answer means that you don't recognize that Jesus even existed. I don't know how you missed it, it was in all the papers.
