The principle here is carried further in that if a believing spouse opts for divorce and refuses to stay in the marriage, then you are free to remarry.
You cannot be bound to one who refuses the relationship and leaves.
This still leaves the whole question of a divorced person, man or woman, being able to get married again.
There are several passages that need to be taken together in order to get a complete picture on what the Bible teaches.
Paul deals with another example in which divorce is allowed and the believer in Jesus is free to remarry.
In 1 Corinthians -15, Paul says that if a believer is married to an unbeliever and the unbeliever wants a divorce then you are to let them leave.
We are just not always willing to work at it as we should.
What God, through Moses, intended to do was manage a bad situation as best as possible.
Second, it took pressure off older women to find a husband at their age and receive the support of the church.You are not bound to that relationship any longer, but in fact free.That freedom is understood as the freedom to remarry.In the Jewish culture in which Jesus spoke, the whole reason for a divorce was to be able to remarry.
The certificate of divorce that He mentions was what gave a person the freedom to remarry.In the Sermon on the Mount, Matthew ,32, Jesus makes it clear that if a spouse is guilty of sexual infidelity then the offended spouse is free to divorce.
