Genesis 2:24, I wouldn't even begin to assume what "one flesh" means to God. But I also won't assume that it means something eternal. For in the New Testament, we are told that if one spouses died, they can get remarried. Does that mean the second wife/husband are not of "one flesh"...I don't know. I don't know what "one flesh" mean to God.
Ecc 3:14, I'm not quite sure that we can interpret that verse that way...God created earth and it will not last forever, God created humans and we certainly do not last forever. I'm not sure we are interpreting that verse correctly.
Mark 10:9--we can interpret that as not divorcing because God has joined them together, especially since that's what Christ says in verse 10.
1 Cor. 11:11, I don't think that's speaking about a marital relationship because it is in the context of head covering and authority, reach 1 Cor 11:1-16,
1 Peter 3:7, seeing as we inherit eternal life, that would make sense.
But I don't know what will be in heaven and how things are, and we aren't really told, so I'm not going to assume anything beyond that and eternal marriages is not something we are told in scripture.
Does it make sense that a man is to cleave unto his wife, and they shall be one flesh, only to be eternally ripped apart at death?
??? We are not told what happens in heaven when it comes to marriages, so I am not going to assume anything or go beyond what is in scripture.
Does whatsoever God doeth, it shall be forever, apply to everything God does, except when he joins a man and woman in the marriage bond?
Again, I don't know if we are interpreting this correctly, because some things we know won't last forever...like the earth and being alive. And I don't know what will be in heaven, except the Glory of God there.
If it is so that, whatsoever thou shalt bind on earth shall be bound in heaven, does, "whatsoever," mean everything, except marriage?
That command was given to Peter, for he was given the keys to the kingdom...so what He did with those keys (symbolically) in the book of Acts--He preached!!!
If marriage, and the relationship between husband and wife, is so important that the Lord said of it that what therefore God hath joined together, let not man put asunder, why would he put it asunder in heaven?
I don't know anything about marriage in heaven for we are not given those plans from God. The only thing that I have found about marriage after death, are those verses in Matthew 22.
Does it make sense that neither is the man without the woman, neither the woman without the man, in the Lord, except when they are in heaven?
That phrase is in the context of authority and head covering. First Adam was created by God, then Eve formed by the ribs of Adam by God and then everyone else came from Eve (woman), through the birthing process, given by God; so men and women are very depended on each other. Because of that, even if I were not married in the Corinthian church at that time, my hair (women) would be my head covering.
And if husbands and wives are heirs together of the grace of life, does it make sense that this only applies to their mortal existence, but they are not heirs together of the grace of eternal life?
"heirs according to the promise" meaning that we inherit eternal life, that implies our spiritual existence. You will still be in heaven together, whether that means you will be considered "married" in heaven, I don't know, we are not told that in scripture.
Most importantly, what would be the point of comparing the relationship between Christ and his church, which is of an eternal nature and unity, to something that is without eternal consequence and has no future beyond mortality? Why would the Lord represent the eternal relationship between himself (the bridegroom) and the church (the bride) with something that is only temporary, and is severed and made null and void forever at death? Why compare a binding eternal relationship, to something that is completely dead and over, as marriage would be, if marriage could not, and was not intended to, be a lasting bond that continues beyond the grave and throughout all of eternity?
See, this idea doesn't really make sense. If Christ is the (bridegroom) and the church (body of Christ) is the bride, why then do we think there will be many marriages within the marriage of Christ and His church in heaven? I can be completely misunderstanding what it means for the Church to be His bride, Lord knows that is something that I can't wrap my head around it.
And as for asking me why Christ would compare the marriage relationship to eternal relationship between Him and the Church, if the marital relationship between man and woman is not eternal? I don't know. That's like me asking why God gives us a description of heaven through descriptions that we would understand like "pearly gates" and "golden streets" when this world is not eternal? It help us understand heavenly things when we are mortal beings.
