Ephesians 5:29-33

For no one has ever hated his own body but he feeds it and takes care of it, just as Christ also does the church, for we are members of his body. For this reason a man will leave his father and mother and will be joined to his wife, and the two will become one flesh. This mystery is great – but I am actually speaking with reference to Christ and the church. Nevertheless, each one of you must also love his own wife as he loves himself, and the wife must respect her husband.
