When you talk about Jews, you seem to forget, the Jews have been very much punished for there rejection of God's Messiah. And for going after there own God. So when you say hes coming back for the Jews, while that is partly true, and not many it would seem 144,000. They arent exactly favoured in the way you think, they have rejected Gods new covenenant and instead embrace the old one in a sense idolatry, and putting themselves on a pedestal as special, not dissimilar to carrying on the Pharisee's tradition.
The 144,00 are not genetic Israelites. Here is why:
1. There are no genetic Jews from all the tribes of Israel in the world today. There hasn't been for more than 2500 years. 10 tribes were completely destroyed hundreds of years before Jesus even came to earth. They were carried away by the Assyrians,
"In the ninth year of Hoshea, the king of Assyria took Samaria and carried Israel away to Assyria, and placed them in Halah and by the Habor, the River of Gozan, and in the cities of the Medes" (2 Kings 17:6). You would be hard pressed to find even one pure descendant from the tribe of Gad, Asher, Naphtali, Manasseh, or Simeon-much less 12,000 of them! They became extinct. They are not going to miraculously exist again.
2. Even from the two tribes that remained (Judah, Benjamin, Levi never counted because they never inherited land as priests) which made up Judah, after they were taken captive by Babylon, not all of them returned home, just some of them. That further decreased their number.
3. When Jerusalem was attacked by Rome, about 40 years after Jesus' ascension (this is when the temple was destroyed for the last time), many Jews scattered around the world and intermarried too. That is why its well known the Jews in the nation of Israel today are mainly Ashkenazi Jews who are mainly of European decent. Most of them have no Middle eastern DNA in them at all.
4. Another strong clue that Revelation is not speaking of the literal Israelite tribes is that in the Old Testament, the 12 tribes were very unequal in population numbers. Judah was very large, while Benjamin was very small. God divided the promised land in proportion to each tribe's needs. But the 144,000 is composed of 12,000 per tribe, right across the board.
5. The Bible is clear especially in the New Testament that all who accept Christ as their personal Saviour, obey and follow His precepts, they are Abraham's seed. So who makes up the 144,000? The answer lies in God's promises that were once for literal Israel but now apply to spiritual Israel, the church, the righteous, the saints etc. The prophecies in the New Testament focus on the children of faith whether they are Jews or Gentiles. Jews are not separated from Gentiles anywhere in the New Testament. The people who will be separated from each other at the end are the righteous from the unrighteous, the just from the unjust.
Romans 2:28- 29, "For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit."
Galatians 3:29, "And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
The 144,000 are a special group of people called at the end of time that God will use to spread the Word to every part of the globe. They are faithful and keep the commandments of God and do not compresses their beliefs even through the great tribulation, even when they are persecuted. They will live through the great tribulation and will be alive when Jesus comes back, therefore they will never taste death (
Revelation 7:1-4, 14:1-5). They are not a special group because they are genetic Israelites.
