It is only our Father in heaven who can marry people, it is an act performed in heaven, and is thus eternal.
It is not bodies of flesh that are married but children of light in the Lord.
25
When the dead rise, they will neither marry nor be given in marriage. Instead, they will be like the angels in heaven.
It is very very beautiful, the love between brothers and sisters there is far beyond anything on earth
There we lend of Gods love, to love sisters and brothers.
There we may be married to many simultaneously, there no man is without a woman, and no woman without a man:
1 Corinthians 11:11 Nevertheless neither is the man without the woman, neither the woman without the man, in the Lord.
So if God has married you, then you are married, no one can overrule God.
But you need not marry on earth because Father has married you in heaven, we may live thousands of miles away
from a sister on earth, and never meet her in the flesh, but still be married by God to her
God will often marry/ unite sisters and brothers in the body of Christ who are making progress studying the bible together
when a certain sister is acting a perfect help meet for a certain brother God will often, (or always I do not know) marry them
in the body of light. They are being obedient to God:
18
The LORD God also said, “It is not good for the man to be alone. I will make for him a suitable helper.
If a sister and brother wants to marry on earth, it is best if they can get confirmation directly from God that He already married them in heaven,
if not they may get confirmation through a prophet that they have trust in.
If not they may make sure they when they choose a spouse that they can cooperate well with them reaching for God, study the bible, making progress
on the way. And that they see things in the other that they know are pleasing to God. And that they share great love with in the body of Christ.
It is not good for a sister or brother to choose a spouse from outside of the body of Christ, or to choose like many atheists do because of looks,
wealth, homeownership, or because of other treasures of the earth.
A sister and brother must put the treasures of heaven first, in this matter as in other matters, if they do not do that, they can be almost certain that they go
against the will of Father, and thus will never be married by Him:
9
Therefore what God has joined together, let man not separate.”
