Good morning, Forest, and you are welcome, though I wonder what you mean.
Could you please clarify? Do you mean the Jews? Would they not be required
to lay hold of faith by grace in the shed righteous blood of Jesus Christ?
I believe the scriptures to teach that the blinded people of the house of Jacob/Israel is spiritual Israel, that will regain their sight to see the truth by the teaching of the remnant of the house of Jacob/Israel (Zeph 3:11-13). before Christ returns the second time
Because it is by the grace of God, there is nothing that mankind can do to gain an eternal inheritance of heaven, however, I believe that the redeemed, as they live their lives here on earth do have to repent (not to save themselves eternally) but to follow God's instructions before they can enjoy a fellowship with God.
