UPDATE 4: When it comes to sex between a man and a woman, the Bible teaches us that two things must happen before sex is permitted, there must be the spiritual union of the man and the woman and there must be the marriage ceremony of the man and the woman. We all know what the marriage ceremony is but what is spiritual union? Spiritual union is the ability shared by the man and the woman to spend the rest of their life with the other person. This ability is given by God simultaneously to the man and to the woman.
