....people who have lived the Law every waking moment of their lives.
What you are describing are the Jews of the Bible that loved Jehovah's law-and not the Babylonians walking around today with "Shabbes keys" within their eruvs, mobbing, maiming, blinding, spitting at, and encroaching on the freedoms of Jehovah's Witnesses (missionaries).
It is well established by Christian interpretation of the Bible that the law ends in Christ, the seed of Abraham ("to your seed I will give the land." -as explained in the "Epistles.") The "jews," that is to say, the natural descendants of Jacob(and Rahab, etc), play no other role than that- a maginificent one indeed- (write the Bible and mother the Messiah.) in God's books. Modern Halachic jews in-spite of their adherence to their version of the law of Moses (no to brother-in-law marriage- yes to pilegesh depending on the Rabbi. ) have no role in God's wok. It is purely academic how Judaism today interpret the Bible, they have no authority and no Holy Spirit. The JW proclaim both. Judaism's modern version of Israel is a Republic who's Shomer is nuclear weapons and UN-hamstrung horses (mute ones) -and not Jehovah of Armies.
Anyway, that is my just view. We will see who's view prevails.
