The beginning of the book of Genesis contains the account where God created man and woman, and the first marriage: “But for Adam no suitable helper was found. So the Lord God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs and then closed up the place with flesh. Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man.
and flesh of my flesh;
she shall be called ‘woman,’
for she was taken out of man.’
Jesus affirmed this when discussing marriage and divorce with a group of Pharisees: “’Haven’t you read,’ he replied, ‘that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.’” (Matthew 19:4-6, NIV).
1. Human sexuality was designed to be expressed between one man and one woman, united together for life. The Bible contains many stories of the miseries that arose because of deviant sexual acts such as polygamy (Genesis 29-30, 1 Samuel 1:1-8), adultery (2 Samuel 11), prostitution (Judges 11:1-3), rape (Judges 19; 2 Samuel 13), etc. Sex was designed as a uniting bond between a man and his wife (the Hebrew root words used in Genesis 2:24 are “ish”, meaning “man, male” and “isha”, meaning “woman, female”).
