That's not what it says in Revelation. In chapter 6 the resurrected church is up in heaven watching as Jesus opens the 7 seals on the scroll, ending with "The kings of the earth, the princes, the commanding officers, the rich, the strong, and every slave and free person, hid themselves in the caves and in the rocks of the mountains". Then in chapter 7 it says, "After this ...", then the 144,000 Jews are sealed. Therefore that is a still future event; none of the 144,000 have lived during the Gospel Age, going back to the first century AD.The 144,000 were gathered from the first century onward,
You are confusing the resurrected church with the 144,000 Jews. The 144,000 are men (Revelation 14:4 tells us that the 144,000 "are those who were not defiled with women, for they are virgins") and will remain human, living on the earth. There is no mention of them being changed to spirit beings and living in heaven.Many among the elect are females whilst on earth, but they are called "sons" even though their spiritual resurrection means losing all their earthly identity...no gender, nationality or social status will identify the144,000 "joint-heirs" once they are in heaven. They will be like the angels in that respect.
Revelation tells us that the church will be resurrected and be in heaven with Jesus, serving as priests and kings in God's kingdom (joint heirs with Jesus). Then the 144,000 Jews are sealed and protected and preserved during the Great Tribulation on the earth - Revelation 9, "(4) They were told that they should not hurt the grass of the earth, neither any green thing, neither any tree, but only those people who don’t have God’s seal on their foreheads. (5) They were given power, not to kill them, but to torment them for five months. ... (18) By these three plagues were one third of mankind killed: by the fire, the smoke, and the sulfur, which proceeded out of their mouths".No wonder Christendom rejects the idea of a ruling class in heaven who are specially chosen....it means that the majority of mankind including all who identify as Christians, will not go to heaven, because you have to be "called" by God for that role. (Heb 3:1) Only those taken into the "new covenant" will rule with Christ as a "royal priesthood and a holy nation" in heaven. "Kings and Priests" who will rule with Christ.....all personally chosen by God so that humans will have the best rulers this earth has ever seen.
In Revelation 7 it tells us of "a great multitude, which no man could count, out of every nation and of all tribes, peoples, and languages, standing before the throne and before the Lamb, dressed in white robes, with palm branches in their hands", and that "These are those who came out of the great tribulation. They washed their robes, and made them white in the Lamb’s blood. Therefore they are before the throne of God, they serve him day and night in his temple". So there will be an inumerable number of people who will have faith in Jesus during the Great Tribulation, who will be rewarded with an eternity in heaven. They will have missed out on becoming joint heirs with Jesus and becoming adopted sons of God (having a similar immortal spirit nature as Jesus has), and they won't have a priestly and kingly role in the kingdom, but they will nevertheless be with God in heaven, serving God in his temple. Jesus, the "Lamb who is in the middle of the throne shepherds them, and leads them to springs of life-giving waters" - could these be the other fold that Jesus spoke about? John 10:16, "I have other sheep, which are not of this fold. I must bring them also, and they will hear my voice. They will become one flock with one shepherd".
There will be millions of people, Jews and all non Christians that have lived during the last 6,000 years, who will be resurrected to life during the Millennial Age, including those who survive the Great Tribulation but did not have faith in Jesus, who will have the opportunity to live forever on the earth as humans. These will be who the resurrected church will rule over, under the leadership of Jesus, during the 1,000 years (Revelation 5:10, "made us kings and priests to our God, and we will reign on the earth”; Revelation 20:4 - "They lived and reigned with Christ for a thousand years"). It is God's plan for there to always be human members of His family living on the earth, as well as spiritual members of His family living in heaven.Revelation 21:2-4 refers to mankind enjoying the benefits of Kingdom rule...Everything will go back to the way it was meant to be....
The "height of absurdity" is the belief that all Christians are heaven bound....why did God put us on earth if he was only going to take us to heaven? He already has a very large family of spirit sons, serving him in heaven.
Why did he put humans on earth?
