Jewish is not a race. There are black Jews, white Jews and Asian Jews. It is true Jews were mostly black and semitic originally, but that has changed over the centuries obviously.
Welcome Aviva! So glad you came. Glad you are willing to talk to some of us "Jesus Freaks". Do you think you might have looked into Christianity if you had not been born into Judaism? We gentiles believe that we are all born into sin and must come into Christianity by choosing to invite Jesus into our hearts.
From reading the Old Testament, I would agree with your assessment about how Jewishness and Judaism were always inextricably tied together. God never tolerated atheism from any child of Abraham. Atheism was never an option for Jews in the eyes of the Father.
We, as Christians, do not believe that being outside of Christianity is acceptable for any human being since Jesus (who we believe will fill all your requirements very soon) came to Earth and died for everyone 2000 years ago. We believe that all who reject the Father's gift (Jesus) will be damned to eternal punishment in a Lake of Fire.
Have you ever considered reading the Gospel of John in our New Testament? John (a Jew himself) writes much about the future of Jews in another of his New Testament books;
The Revelation.
Revelation, Chapter 12
1And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
2And she being with child cried, travailing in birth, and pained to be delivered.
3And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
4And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
5And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
6And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.
7And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
8And prevailed not; neither was their place found any more in heaven.
9And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
11And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
12Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
13And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
14And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
15And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
16And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
17And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
