The answer
Sex is the most spiritual thing in life, and the holiest of holies in human nature. But in society today, it has become distorted, corrupted, substantialised and humiliated. Originally when God created Adam and Eve, He developed a triangular relationship : God, man, and woman. In this relationship, love passes from God to man, man to God, God to woman, woman to God, man to woman, woman to man. This is the holiest relationship, and the one which represents Christian love and marriage. If, however, man/woman separate themselves from God, there will be no spiritual union, only ego and selfishness. The result, in this case, will be that the four components present in humans, (body, mind, psyche, spirit) will be disturbed because there is no discipline: the body will be crying, the psyche is sorrowful, the soul is agonising, and the mind is trying to philosophise the sin. In such a situation, much sexual deviations will occur, but without happiness, because sex is no longer unifying, but dividing, and this sin will always be present because there is no grace inside such people.
Sex, as God planned it, was to be the medium for love, happiness and unity. But sadly society has corrupted this by emphasising that lust is love. According to the Bible, there are three Greek words for love: EROS, which is the lusty, sensual love; PHILIA, which is the human love without desire or spirituality, as occurs between people generally; and AGAPE; which is the Christian, spiritual love, unifying and unselfish. Today, however, non-Christians are living in Eros, thinking that this will lead to marriage, but what it results in is a broken marriage. Therefore, as Christians, we refuse this erotic love because it is body to body, instead of person to person. What you are seeing around you is not sex as God meant it to be, but uncleanliness. And you always notice how they are never happy or satisfied; but always thirsty and greedy for more. For this reason, sex today divides the people because it is not spiritual, but deviated and negative. This is why Christians never enter into sexual relationships outside of marriage.
