Yes Christians are not called to divorce to wife.. Our God is not leaving us forsaking us.. Even we do wrong He is forgiving us and doing better things in our life.. That's why we are fallowing God. Only if you found adultery we can forsake our wives (this is sad in old testament).. But according to word.. if we go to study in deep,, many times we are getting forgiveness.. In my view.. if we are saved.. we have to guide our wives to truth.. that is also service to Lord.. If you fail in your home how you can rule or talk in the assembly of God.. Do according to Word.. Jesus is not accepted the divorce to wives,..
Mar 10:2 And the Pharisees came to him, and asked him, Is it lawful for a man to put away his wife? tempting him.
3 And he answered and said unto them, What did Moses command you?
4 And they said, Moses suffered to write a bill of divorcement, and to put her away.
5 And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept.
6 But from the beginning of the creation God made them male and female.
7 For this cause shall a man leave his father and mother, and cleave to his wife;
8 And they twain shall be one flesh: so then they are no more twain, but one flesh.
9 What therefore God hath joined together, let not man put asunder.
Even we are saved in Him we are doing wrong, when we are doing wrong that means we are in adultery with worldly tings.. God is forgiving us.. We are not perfect.. but grace is doing all for us.. PLEASE DO AS LORD IS DOING FOR YOU..
