In religious matters, sources of information available to us reveals that the majority has always been wrong.
The ones that were correct was always a very small group or the minority. Just like Noah and the other 7 persons that were on the ark.

Noah preached for 120 years that the flood was coming. The majority of the people didn’t believe him. There may have been millions of people alive at that time and they all died without knowing God. The 8 people on the ark are the only ones that made it.

The Bible tells us that the 144,000 are people who have the seal of the Living God and do 2 things. They follow God’s Commandments and follow Jesus Christ. Revelation 12:17, Revelation 14:12.

The number is represented by 12,000 from each of the 12 tribes of Israel: Judah, Reuben, Gad, Asher, Naphtali, Manasseh, Simeon, Levi, Issachar, Zebulun, Joseph and Benjamin.

The Bible says in Revelation 14:4 “They are not defiled by women; for they are virgins.”
This does not mean that they are celibate (have no sexual relations), or that they are unmarried Jews.
(This would go against Paul’s teachings in 1 Tim 4: 1, 3) A woman in the book of Revelation is a symbol of a church (Rev 17.)  So the meaning is that they are not defiled by an apostate church.

The 144,000 represent a final remnant of God’s Israel in Spirit (Spiritual Israel) and will still be alive when Jesus returns in the clouds. They won’t be defiled by deceptions and false prophecies. They will have been transformed into “Spiritual Israel” (just like Jacob was transformed and his name was changed), and have come out of spiritual Babylon.  Revelation 18:4-8  They will not live like the rest of the World, God is first place in their lives.

And there shall be a time of trouble, Such as never was since there was a nation, Even to that time. And at that time your people shall be delivered, Every one who is found written in the book. And many of those who sleep in the dust of the earth shall awake, Some to everlasting life, Some to shame and everlasting contempt. Daniel 12:1, 2

The 144,000 will serve the same purpose as the 12 Apostles

Evidently, this great multitude who come out of great tribulation are converted under the preaching and influence of the 144,000. Shortly after Pentecost, the 12 apostles reached a great multitude, then there followed a great persecution (Acts 8:1). Shortly after the Holy Spirit is poured out on the 144,000, a great multitude will be converted and then comes the great tribulation.

We are to love our Jewish brothers and sisters, but people are wrong in keeping an eye on the middle eastern city of Israel. They are thinking just like the people that didn’t know or recognize that Jesus was talking in a spiritual sense and not a literal sense.

For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit Romans 2:28,29

Remember Galatians 3:29 We are all Abraham’s seed. All true Christian’s are Spiritual Israelites. In Exodus 19:6 we see “And you shall be to Me a kingdom of priests and a holy nation.”

The book of James says this: James, a servant of God and of the Lord Jesus Christ, to the 12 tribes which are scattered abroad, greetings James 1:1
