Matthew 19:1 Now when Jesus had finished these sayings, he went away from Galilee and entered the region of Judea beyond the Jordan. 2 And large crowds followed him, and he healed them there. 3 And Pharisees came up to him and tested him by asking, "Is it lawful to divorce one's wife for any cause?" 4 He answered, "Have you not read that he who created them from the beginning made them male and female, 5 and said, 'Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh'? 6 So they are no longer two but one flesh. What therefore God has joined together, let not man separate." 7 They said to him, "Why then did Moses command one to give a certificate of divorce and to send her away?" 8 He said to them, "Because of your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. 9 And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery." 10 The disciples said to him, "If such is the case of a man with his wife, it is better not to marry." 11 But he said to them, "Not everyone can receive this saying, but only those to whom it is given. 12 For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let the one who is able to receive this receive it."
Jesus answered the question about divorce for any cause with the scriptures. This is an example we are to follow. Questions about how we live our lives always need to be answered from God's written word, the Bible. Only 4% of U.S. citizens do this.
Jesus' teaching concerning divorce is not popular in our culture today. Jesus took His questioners back to Genesis 1:1, 26-27; 2:24. The Creator made a man and a woman to become one flesh. What the Creator has joined together man is not to separate (Matthew 19:6). Jesus gave one reason for divorce with the ability to remarry in Matthew 19:9, the act of immorality called adultery.
The reason why people divorce is because of hardness of heart (Matthew 19:6). What is hardness of heart? Hebrews 3:13 instructs us that the deceitfulness of sin hardens our hearts, hardens us towards God. Being hardened against God means we don't seek to live His way, but live as sin dictates. Living according to sin ultimately leads to death.
Some people don't marry in order to avoid the difficulties of marriage. These people can live without sexual relations because of how they were born, or because of what someone did to them or because of their own choice (Matthew 19:11-12). In 1 Corinthians 7:1-5 Paul calls people without the ability to forego sexual relations and not burn with lust to get married and satisfy the sexual needs of their partner and thus their own. If a person seeks to live a celibate life and is unable to do so they will be tempted to sin by Satan.
Being married is difficult. It is the best place to be grown into the likeness of Christ. A successful marriage is empowered by the Holy Spirit and instructed by the word of God (1 Corinthians 13:4-7; 16:14; Ephesians 5:22-33; Matthew 28:20). God's will is good, pleasing and perfect (Romans 12:2b). Marriage God's way is worth the effort. Make the attempt to live in marriage God's way and He will fulfill your attempt with His power.
