What do you mean, *Where does your faith come from*?
Everyone has faith. It's simply a matter of what it's put in.
I'm pretty sure observant Jews revere the Word of God, what we call the Old Testament.
So, if the Bible is to be dismissed, where else do you propose that we learn about God? What other special revelation is there to give us those details?
You mean like...I don't know...the pillar and bulwark of the truth?
This is not about dismissing the Bible. This is about the weirdness of a faith in a Bible that rests on itself.
Go out and find for me an orthodox Jew who believes his faith because he read all about it in the Torah. Go on. I’ll wait.
