I agree. I believe the New Testament hints that when it says "now we see dimly as through the glass..." but in the future the veil will be lifted and we shall see clearly. Certainly, in the presence of God no one religion would be needed.
But Judaism does not teach heavenly bliss. Olam HaBa, the World to Come, is not in the heaven, or in the presence of God, but here on earth. And the way they see it, the Jews will still be the priestly nation, and the Gentiles their Noahide followers.
The Jews believe that the nature of God's Covenant with Israel does not change, so they are forever to be a priestly nation. They also believe that by that Covenant they are ontologically made different from the rest of humanity, namely that they are ordained by birth.
Yes..I have read about the Olam HaBa, personally IMO it sounds like People will still have *Dominion* over other’s which does not work in our human condition...
Maybe Jews and Gentiles will be on the earth in this kind of state Olam HaBa but I hope as a Christian to be in heaven.
