I have a question regarding marriage in heaven. In Matthew 22:30, Jesus says that at the resurrection people will neither marry nor be given in marriage; they will be like the angels. So is marriage just an earthly union, or will those who are married remain married in heaven? Will marriages endure in heaven, or will the husband and wife be just friends (or brothers and sisters in Christ)?

I don’t think the scriptures tell us much about this. Matthew 22 says people won’t get married. (No change in marital status?) I wonder too about people who have been married twice: a widower who remarries, for example. How will it work out with the various spouses?

Sorry to answer your question with questions of my own. Apparently in God’s eternity this will be no problem. It's certainly beyond me to figure it out!
