Mark 10:1 And he arose from thence, and cometh into the coasts of Judaea by the farther side of Jordan: and the people resort unto him again; and, as he was wont, he taught them again.
Prov 29:18 Where there is no vision, the people perish: but he that keepeth the law, happy is he.
Mark 10:2 And the Pharisees came to him, and asked him, Is it lawful for a man to put away his wife? tempting him.
Mark 10:3 And he answered and said unto them, What did Moses command you?
The pharisee was out to discredit Jesus, he chose a topic of controversy, both then and now. The pharisee was to uphold the law; what did Moses command?
Mark 10:4 And they said, Moses suffered to write a bill of divorcement, and to put her away.
Mark 10:5 And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept.
Moses allowed divorce because of your sinful hearts, but what did God say? From the beginning God ordained marriage.
Mark 10:6 But from the beginning of the creation God made them male and female.
Male and female, not the abomination of same sex marriage, God ordained that a man and woman should become one flesh.
Mark 10:7 For this cause shall a man leave his father and mother, and cleave to his wife;
Mark 10:8 And they twain shall be one flesh: so then they are no more twain, but one flesh.
To cleave is as to be glued together, and they are to leave father and mother and become one flesh. The bond of husband and wife is greater than a child and parent. Not only are they to become one flesh, but also one heart and mind. This is why we must marry a believer.
2 Cor 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
Mark 10:9 What therefore God hath joined together, let not man put asunder.
It is ordained of God, no man shall put this institution of God away, nor shall mankind promote separation and divorce. These are evil worldly views.
