True Godly Marriage
There are so much confusion in the church today concerning marriage, divorce and remarriage. The Bible is clear that true marriage is something that God must put His stamp of approval upon, or else the couple are living in fornication or even adultery.
True marriage must be approved by God Himself
In God's Word, we learn that only God is able to truly join the two persons together in Holy matrimony:
Matthew 19:6, "Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder."
This is not something we can do, our legal system can do, or anybody else here on earth... only God Himself can join two people together in true Holy matrimony.
Divorce? In the Bible?
That's right! Even though divorce was never meant to be from day one...
Matthew 19:7-8, "They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away? He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so."
...divorce was still acceptable when somebody married another person whom was out of God's will for them. In Ezra, we see an example of where the men of Israel went off and took up foreign wives which God hath not approved of for them, and they ended up sending back (divorcing) those foreign wives:
Ezra 10:10-11, "And Ezra the priest stood up, and said unto them, Ye have transgressed, and have taken strange wives, to increase the trespass of Israel. Now therefore make confession unto the LORD God of your fathers, and do his pleasure: and separate yourselves from the people of the land, and from the strange wives."
True marriage cannot be undone or broken
The Bible is clear that the tie between man and woman that God forms in Holy matrimony is not something that can be broken:
Matthew 19:6-9, "Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so. And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery."
Notice that because this tie is not broken, is it impossible to divorce a truly married couple (in God's eyes), and remarry them to somebody else. If we try it, they will end up committing adultery. Why? Because the true marriage tie God formed was never broken. You would still be married to that person that you divorced, thus any other attempts to marry somebody else would in vain, and if you have sexual relations with them, it is adultery in God's eyes:
Matthew 19:9, "And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery."
We cannot go before God and ask Him to break off a true marriage that was of Him. It will not work, and we will end up committing adultery, because the true bond that God formed will not be broken. There is only one exception where God will break up that which He hath joined together, and that is if a spouse is found being unfaithful, which I will explain below.
Mercy from an unfaithful spouse
God has allowed an exception for divorce because of fornication for the sheer sake of mercy:
Matthew 19:8-9, "He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so. And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery."
If a spouse is found to be unfaithful, then there is an option to opt out of the marriage, simply because God is merciful and does not expect us to stay married to an unfaithful spouse.
If a non-believing wife divorces a believing husband
The Bible also provides an exception in a case where a non-believer is married to a believer, and the non-believer divorces the believer. In such a case, the believer is not under bondage to the non-believer:
1 Corinthians 7:15, "But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God hath called us to peace."
Can God form a marriage between unbelievers?
Absolutely! They will by no means experience God's best for their marriage until they come to Christ, but I wholeheartedly believe that God can put two people together even if they aren't Christians. My parents for example, are heading for their 50th wedding anniversary, and yet neither of them were committed believers when they were married. Even though my mother had an experience with the Lord as a child, she wasn't a committed believer at the time she married my father. My father makes it clear that he "knew that he knew" that my mother was the one that was meant for him. Later on in life, both of them gave their lives to Christ and served the Lord together. It has been an outstanding marriage, and yet it was set into motion long before either of them became committed believers. So yes, I believe God can join non-believers together.
Can a believer be married to a non-believer in the eyes of God?
Absolutely! The Bible even tells us that the unbelieving spouse is sanctified by the believing spouse, clearly showing us that the two can be married in the eyes of God:
1 Corinthians 7:14, "For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy."
We are not to purposely marry a non-believer!
God's Word is also clear that we are not to purposely go out and marry a non-believer. If we are already married to one, that's one thing, but if we are planning to marry one, that's another story.
2 Corinthians 6:14, "Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?"
A really good parable: "Who are you married to now?"
Let's say that you're a Christian woman who's been married twice. Your first marriage was to a guy who was in rebellion, which was clearly not a good choice. Your marriage with him lasted 2 years, and then ended in divorce. There was no fornication on either side of the fence, but it turned out a mess none the less. A few years later, you re-marry a wonderful man who dearly loves the Lord, and decide to have a family together. Ten years later, you have a beautiful Godly family, and a wonderful husband who cares for you and loves you deeply. The problem is, if you were truly married to the first husband, and since Godly marriages cannot be put asunder, you would be living in adultery with this man that is now your husband. Either that, or you were living in fornication back with your first husband (whom you weren't truly married to in God's eyes).
The big question is, which of your husbands did God join you to with a Holy tie that cannot be broken? If it were the first husband, then you would be living in adultery by living with your current husband, but if it were the man you are married to now, then you've committed fornication with the first 'husband'.
It's important to marry the right one
If God must approve of your marriage, and once united with somebody in true Holy matrimony you cannot be separated from them, then it is 100% vital that you make sure He's put His stamp of approval on your attempt to get married. If He has not approved of it, then you are going to live in fornication or even adultery with the other person!
A Godly spouse comes from the Lord
Proverbs 19:14, "House and riches are the inheritance of fathers: and a prudent wife is from the LORD."
Disclaimer: I did not write this teaching to cause couples to rush out and get a divorce, or for singles to hurry up and marry the first person they have a peace about. Please do not do that! It is quite possible for you to be married to the right one, and have the enemy trying to separate that which God hath joined together, as he is known to do such things. Wait upon the Lord, seek Him on the matter, and wait for His reply. Do not rush out and do something that you will later on regret! Many factors can be involved in any given situation... for example, maybe you have a less than perfect relationship with your wife, and are still attracted to somebody whom you've had sexual relations with years ago... it's quite possible that an unclean soul tie is drawing you back to the wrong one. That is why it is 100% vital that you hear from God before making a move. If you rush out and divorce the one that God has joined you to... it won't work, and you will be out of God's will. That person could then run off and marry Mr. Wrong, and end up committing adultery with them, while your stuck living single for many years... deeply regretting the choice you've made. Perhaps the best advise in marriage counseling, is for both the husband and wife to clean up anything their own lives that is not good (repent) and get their relationships with the Lord in order, then watch as God helps them repair their own relationships with each other. If your own life is not in order with God, then don't even think of making a move until it is!
