144,000 of heaven, What of earth?

 Evidently much is misunderstood by many. Know this, that Jesus the Christ was sent by His God and Father, JEHOVAH [John 8:42, John 6:38, John 20:17, 1 Pe 1:3], to provide a propitiatory sacrifice on behalf of obedient mankind. By Christ's submissive and obedient life, the charges made by Satan, were all proven wrong.
Christ was sent to begin a reconciliation to JEHOVAH, of the things in the heaven and things of the earth.
Christ, however, was sent principally to gather those of New Jerusalem, the 144,000, who will rule as kings and priests with Him [Revelation 20:6].
The sealing of those who belong to this group, those who are to be born again as spirit beings, continue up until the beginning of the Great Tribulation [Re 6:10, 7:2, 3]

In the meantime, MOST persons [the Bible says no man was able to disclose the actual figure] will have  the prospect of living on the "new" earth.

2 Peter 3:13 (King James Version)

 13Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.

At Genesis 49: 3-27 we see the NAMING of the TWELVE tribes of the NATION of Israel.

They are; Reuben, Simeon, Levi, Judah, Zebulan, Issachar, Dan, Gad, Asher, Naphtali, Joseph and Benjamin.

When we look at the account at Revelation 7: 5 - 8, we NOTE a difference, Manasseh has replaced Dan. Manasseh was the firstborn of Joseph [Genesis 41: 50, 51, 52.].

Covenants

The covenant that pertains to LITERAL or physical Israel puts them in a special relationship with

God Almighty, Exodus 19:6 reads: And you yourselves will become to me a KINGDOM of

PRIESTS and a holy NATION. These are the words that you are to say to the sons of Israel."

This situation has CHANGED however. In Jeremiah 31: 31-34, a NEW covenant is mentioned

[See also Hebrews 8: 6-13; 10: 14 - 36].

More significantly however, when Jesus Christ, the Messiah or anointed One was rejected by

the Jews, the NEW covenant fell on a NEW NATION, SPIRITUAL Israel. According to the Holy Scriptures, the Bible, we read at Matthew 21: 43: This is why I say to you, The Kingdom of God will be TAKEN from you and be GIVEN to a NATION producing its FRUITS; and at Matthew 23: 38 we read: Look! Your house is abandoned to you.

Also, at Acts 15: 14 - 20: Symeon has related thoroughly how God for the FIRST time turned his attention to the NATIONS to take out of THEM a PEOPLE for his NAME. And with this the words of PROPHETS agree, just as it is WRITTEN, 'After these things I shall RETURN and rebuild the booth of David that is fallen down;

and I shall REBUILD its ruins and erect it again, in order that those who REMAIN of the men may EARNESTLY seek Jehovah, together with people of ALL the NATIONS, people who are CALLED by my NAME, says Jehovah, who is doing these things, known from of old.

Please COMPARE Amos 9: 11, 12.

Acts 10: 34, 35 reads: At this Peter opened his mouth and said: "For a certainty I perceive that God is NOT PARTIAL, but in EVERY NATION the man that fears him and works

RIGHTEOUSNESS is ACCEPTABLE to him. Please READ the FULL account.
