1 Corinthians 7:10-11
To the married I give charge, not I but the Lord, that the wife should not separate from her husband 11 (but if she does, let her remain single or else be reconciled to her husband)—and that the husband should not divorce his wife. rsv
Some women must separate from their husbands because their lives and/or the lives of their children are in danger. If they separate from their husbands because of this, they cannot remarry if their husbands divorce them
. The women cannot remarry until their husband dies.
If a husband divorces his wife, he must remain single after the divorce or reconcile with his wife. He cannot remarry until his wife dies.
In that culture, it was the husband who initiated divorce.
There is definitely forgiveness for divorce if the person who caused the divorce is repentant, but the forgiven person is still not allowed to remarry. The forgiven person cannot remarry until his/her spouse dies.
Also, the wronged person in a divorce may not remarry until his/her spouse dies.
That is why Jesus taught:
Luke 16:18
“Every one who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery. rsv
That is why the disciples said:
Matthew 19:10
The disciples said to him, “If such is the case of a man with his wife, it is not expedient to marry.” rsv
That is why Paul taught:
2 Corinthians 6:14
Do not be mismated with unbelievers. For what partnership have righteousness and iniquity? Or what fellowship has light with darkness? rsv
Two people who marry become one flesh. Their one flesh can only be separated by the death of one of them.
If a person has sex with someone else while his spouse is still living, this person is an adulterer. This person commits adultery every time he/she has sex with anyone who is not his/her spouse.
