Matthew 19:3-9 The Pharisees also came to him, tempting him, and saying to him, Is it lawful for a man to put away his wife for every cause? And he answered and said to them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. They say to him, Why did Moses then command to give a writing of divorcement, and to put her away? He saith to 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 to 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.

Marriage is a permanent, life-long union between a man and a woman.  

There has been plenty of perversion of marriage.  Marriage is a life-long union between one man and one woman.

 
• Pre-marital sex is perversion of marriage.
 
• Extra-marital sex is perversion of marriage.
 
• To stir up the marriage-related emotions for any other than your spouse is perversion of marriage.
 
• For one spouse to hurt the other is perversion of marriage.
 
• There are many perversions too terrible to mention here, though they are freely spoken of.  People who have chosen to promote and to follow evil are trying to teach those perversions through every method possible.  We hear them promote these strange activities on TV, on the radio, in songs, in schools, in books, magazines and other print media.
 
• There is no such thing as same-sex marriage even if something called by that name is made legal by a corrupt human government.  
  
 
• Jesus here is pointing out that divorce is a perversion of the way that marriage was designed by God to be.  Sometimes, because of the hardness of the heart of one or both spouses, it is necessary that a divorce take place, but that does not open the door for either spouse to get married again.  Only in the case of fornication is that door opened.  That hardness of heart is a perversion.  If we are soft toward God, he can love your spouse through you.

 
In Genesis 1:27-28, God made man and woman as distinct--and it was very good.  This is obvious.  The creation itself makes it obvous.  How could any fool miss it.  Yet some very intelligent and educated people are totally confused on this issue.  They walk in darkness and have been educated into ignorance.
