The headline of this post is the same as a recent headline in the "Lifestyle" section of MSN (link to article - Caution Inappropriate Subject Matter at Link). The article tries to take a naturalistic approach, focusing essentially on biological explanations.
For example, the article quotes Lisa Diamond, Ph.D., as stating that regarding a woman's desires, "It doesn't appear to be something a woman can control." The article, focusing on these biological explanations, also notes that men seem more "rigid" in these things and women more "fluid."
All this misses the point. The Bible has the answer to why it is that women leave men for other women, and why men leave women for other men. The answer is God's judgment on sin.
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: 27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet. 28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; 29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, 30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, 31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: 32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
How fitting that a society who worships biology, as though biology in itself could provide the answers, is turned over to this perversion of the natural order. God has turned over the minds of this generation to such an extent that these shameful behaviors are no longer the skeleton in the closet, or even an elephant in the living room, but the open talk of all. The article puts it this way, "we've arrived at a moment in the popular culture when it all suddenly seems almost fashionable — or at least, acceptable."
May God forgive us of these sins, and show mercy on us, bringing repentance to our society before it is swallowed up in judgment. There is a solution to this problem: conformity to the Law of God (not out of servile fear, but out of love for our Creator), which may be found in the Holy Scriptures.
