Scientists and advocates of same-sex sexual and marital relationships are making much of recently observed homosexual behavior in animals, and some are suggesting that it proves that homosexuality is genetically rooted and natural (or at least not unnatural) for both animals and human beings. As Al Mohler explains,
The political implications of the issue are clear—those pushing for the normalization of homosexuality want to be able to point to research that would prove the normality of homosexuality in nature.
To draw this conclusion, however, would be a mistake. For it fails to evaluate this homosexual behavior in light of a biblical hamartiology. As Mohler reminds us, we can’t derive what’s natural—or more importantly, what God requires of us—from nature, for the simple reason that the effects of Adam’s sin extend beyond the human race.
The world we know is a world that shows all the effects of human sin and the curse of God’s judgment on that sin. Though the glory of God shines through even its fallen state, nature now imperfectly displays the glory of God. Because of the curse, the world around us now reveals and contains innumerable elements that are “natural,” but not normative. Illnesses and earthquakes are natural, but not normative.
