Rightly understood, sex is one of the greatest gifts God ever gave to a man and a woman. When practiced in the context of a marriage based on lifelong commitment, mutual trust and mutual concern, this natural, beautiful act serves to promote complete oneness. For emotional intimacy, married couples should be committed to alone time together and to regular physical intimacy. When couples seek complete harmony with the heart of God and desire oneness with Him, they can have oneness in marriage as well.
