So what about husband and wife, they wont be togethwr anymore?
Not sexually. Sexuality is for bringing forth children, or bringing forth the fullness of the body of Christ as Christians.
But once the end of the world comes, that will no longer be necessary, desirable nor would it be appropriate since we will likely be brothers and sisters in a bodily way that we are not now.
Notice the question Jesus was answering when he spoke of there being no more marriage in heaven:
Matthew 22:25 Now there were with us seven brethren: and the first, when he had married a wife, deceased, and,
having no issue [child], left his wife unto his brother:
Matthew 22:26 Likewise the second also, and the third,
unto the seventh.
Matthew 22:27 And last of all the woman died also.
Matthew 22:28
Therefore in the resurrection whose wife shall she be of the seven? for they all had her.
The question is phrased as being about the topic of polyandry in heaven, AKA "many husbands at-once"
When Jesus answers the question, he poses two reasons for his answer:
Matthew 22:29 ... the scriptures, ... the power of God ...
Then, for each reason, Jesus gives a more complete answer in the verses which followed.
I'll briefly address Jesus' second response "the power of God":
Since God is the God of the living, eg: Abraham Isaac and Jacob -- if they really could still procreate in the afterlife; then the promise of God here on earth does not need be kept ; for it could be fulfilled in the afterlife.
So, I'm going to say that procreation in the afterlife is inconsistent with what was revealed by God about the necessity of his promise being fulfilled [eg: here on earth ] several times in scripture. The sacrifice of Isaac included..
Now I'll address the first response Jesus gave in Matthew 22:29++ the meaning of marriage; but first focus on the passage Jesus is quoting:
Genesis 2:23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
Genesis 2:24
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be
one flesh.
This passage defines marriage on earth: When a man and woman give to each other their "flesh" and I mean the very slip/clay of their bodies -- that act makes a permanent change to both their bodies so as to unite them.
It also brings about the possibility of having children as a separate consequence.
But also notice that the passage specifies that the "two" become one flesh, and "wife" is singular -- not the three nor four, nor seven (Even under an Oath, or "completely" as the Sadducees asked symbolically by saying seven)...
Therefore: This passage absolutely does NOT support polygamy (many wives at-once) or polyandry.
The passage doesn't even really support divorce as part of God's plan, for divorce was only supposed to be on account of a perversion of the marriage, AKA: porn or apostasy. Such a marriage is never joined by God, but rather marriages joined by God are to be exactly as was Adam and Eve, which means divorce itself can be a perversion/sin in some cases:
Malachi 2:13 And this have ye done again, covering the altar of the LORD with tears, with weeping, and with crying out, insomuch that he regardeth not the offering any more, or receiveth it with good will at your hand.
Malachi 2:14 Yet ye say, Wherefore?
Because the LORD hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet is she thy companion, and the wife of thy covenant.
Malachi 2:15 And did not he[/you] make
one? Yet had he[/you] the residue of the spirit.
And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
Malachi 2:16 For the LORD, the God of Israel, saith that he hateth putting away [divorce/apostasy]: for one covereth violence with his garment, saith the LORD of hosts: therefore take heed to your spirit, that ye deal not treacherously.
So it's important to grasp that Genesis is about
God's plan for marriage -- to bring about a godly seed -- which may in fact be different than man's plan for marriage.
Mark 10:3 And he answered and said unto them, What did Moses command you?
Mark 10:4 And they said, Moses suffered to write a bill of divorcement, and to put her away.
Mark 10:5 And Jesus answered and said unto them, For
the hardness of your heart [AKA because of your transgressions/perversions] he wrote you this precept.
Mark 10:6 But from the beginning of the creation God made them
male and female.
Mark 10:7 For this cause shall a man leave his father and mother, and cleave to his wife;
Mark 10:8 And they
twain shall be one flesh: so then they are no more twain, but one flesh.
Mark 10:9 What therefore
God hath joined together, let not man put asunder.
At this point, there is a set of logical questions which people often don't ask, but I'll just bring up as puzzles to ponder...
Consider: Sexual union brings about children who are not automatically "saved" -- how could this possibly be done in heaven?
Or again: Since Eve was Adam's wife by her very creation, and not sexual union after they were made -- consider the resurrection, when we are created anew and in a new way. On earth, if our fleshly relationship is too "close" it's called incest; and even adopted brothers and sisters do not generally marry; or if the sexual act is immoral it's called adultery, prostitution or sodomy, etc. ( all summed up by the words "hard porn" AKA pornea in Greek )
Yet, think about how close people must be in a legal sense in heaven...?
For the body which rises from the dead is a glorified body, not the body of "flesh" which we have now; and it's the flesh we have now which permits or denies the ability to marry.
Or looked at another way; what woman once in heaven is not already perfectly married (more precisely, covenanted) to one man -- namely Jesus the Christ -- but not by sexual union? For what is only partially true here -- can be perfectly true in heaven:
John 6:56 He that eateth my flesh, and drinketh my blood,
dwelleth in me, and I in him.
I would be very concerned that any woman who would have sexual relations with a man [other than Jesus the Christ, her "husband"] in heaven -- could automatically be an adulteress.
And Jesus never promised sexual relations with anyone; but he does say that those who are about heaven's business [himself included] may avoid sexual relations for the sake of heaven itself.
This might not be obvious at first; but there are no records of Christians actually castrating
themselves [and only one, namely Origen, even suspected of it], yet look what Jesus says approving of celibacy...
Matthew 19:10 His disciples say unto him, If the case of the man be so with his wife,
it is not good to marry.
Matthew 19:11 But he said unto them, All men cannot receive this saying, save they
to whom it is given.
Matthew 19:12 For
there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men:
and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.
Hope this helps stir up some thoughts....
