OK, let us suppose it is said both to women and men, even though it would not fit too much into patriarchal society of those days. But lets take it so.
Now... Two are married. Some situations can happen:
1) One is unfaithful.
a) they wait for a proper divorce and then they start relationships with somebody else
- the one who was faithful can now freely remarry
- what about the one who was not faithful, he/she must stay single for the rest of the life?
They're a lost cause. j/k
The one who is unfaithful would have been stoned in the OT for adultery. But today we don't kill the offender anymore.
As I think this through, the offender is either not a Christian or is a Christian in sin. So marriage counseling would be appropriate.
If the person is a believer, he's to be treated as Matthew 18 states. If after going through the process of correction he does not repent, he's to be removed from the congregation for the hope of repentance and restoration. Love is always the goal.
The offended needs to forgive, but he/she is free to remarry.
But I believe that many of us don't give God the time it takes for Him to work in the heart of the offender and want to scurry along and move on with life. For some, it's a once-chance type thing and you mess up once and your out.
But others do have a heart of love, repentance and restoration. This all can take time, prayer and waiting on the Lord. I've seen a testimony where the husband cheated on the wife and he was a non believer. She waited a couple of years and prayed for her marriage to be restored. Her husband got saved and they began dating and eventually remarried. God is amazing!
Other times, it doesn't work out and the offender doesn't change.
b) they do not wait for a proper divorce and start relationships with somebody else immediately
- does that mean that both of them are unfaithful now and therefore cannot marry anybody to the end of their lifes?
Good question!
I think we have to answer this as to how would believers need to work this through since the instructions are written for those who will obey and that would apply to God's children. Of course, again, marriage counseling would be good. They both need to forgive the other and repent. If they don't, the Matthew 18 principle needs to be applied where they are removed from fellowship in hopes of repentance and restoration. The hope is they would repent and rekindle the love they have for one another.
2. Nobody was unfaithful, they just want to leave for some less serious reasons like "we do not agree with each other"
a) they will divorce and stay single
- can they return to their own marriage again?
Sure, why not? That's the whole purpose....restoring marriages.
b) they will divorce and one finds a new partner
- now can the one who was slower get married with somebody else?
Well again, we're looking to restore the love they had for one another. You can come up with all types of scenarios, I have no doubt of that.
But what's really going on here?
Believers are not holding the marriage covenant as sacred ..... something that needs to be held up as such.
The marriage is the example of God's relationship with His bride, here on earth. I'm afraid we're not doing a very good job of it when we read that there are as many divorces in the church as in the world.
In Matthew 19 we read.....Some Pharisees came to Jesus, testing Him and asking, “Is it lawful for a man to divorce his wife for any reason at all?” And He answered and said, “Have you not read that He who created them from the beginning made them male and female, and said, ‘For this reason A man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? So they are no longer two, but one flesh. What therefore God has joined together, let no man separate.” They *said to Him, “Why then did Moses command to give her A certificate of divorce and send her away?” He *said to them, “Because of your hardness of heart Moses permitted you to divorce your wives; but from the beginning it has not been this way. And I say to you, whoever divorces his wife, except for immorality, and marries another woman commits adultery.”The disciples *said to Him, “If the relationship of the man with his wife is like this, it is better not to marry.” But He said to them, “Not all men can accept this statement, but only those to whom it has been given. For there are eunuchs who were born that way from their mother’s womb; and there are eunuchs who were made eunuchs by men; and there are also eunuchs who made themselves eunuchs for the sake of the kingdom of heaven. He who is able to accept this, let him accept it.”
So we see Jesus takes them back to square one. The two become one flesh. How can you separate the one? God made the two one, how can we separate the union of the male and female who are one in God's sight?
God said that Moses allowed for divorce because they had hard hearts. In the New Covenant, we've been given new hearts, hearts of flesh instead of hearts of stone. The Lord's laws are now written on our hearts and on our minds.
How can we not forgive and how can we not repent of our sin. Within the body of Christ there should always be love, forgiveness and restoration......because we have a new heart, the heart of Jesus.
