One of the first things you learn in Judaism and Christianity is that the eyes and heart are usually terrible guides to the good and the holy. " . . . (D)o not follow after your own heart and your own eyes, which you are inclined to whore after" (Numbers 15:39); "the heart is deceitful above all things . . . " (Jeremiah 17:9).
Supporters of same-sex marriage see the loving gay couple, and therefore do not interest themselves in the effects of changing marriage and family on the children they do not see. And since they venerate their hearts, the biblical ideal of male-female love, marriage and family is of no significance to them.
Animal rights supporters' hearts are deeply moved by the animals they see experimented on, not by the millions of people they do not see who will suffer and die if we stop such experiments.
Likewise, the hearts of the people who support PETA (People for the Ethical Treatment of Animals) are so moved by the plight of slaughtered chickens that the organization has a campaign titled "Holocaust on your plate," which equates our slaughtering of chickens with the Nazi slaughtering of Jews.
For 25 years I have been asking high school seniors across America if they would save their dog or a stranger first if both were drowning. The majority has nearly always voted against the person. Why? Because, they say with no self-doubt, they love their dog, not the stranger. An entire generation has been raised with no reference to any moral code above their heart's feelings. They do not know, and would not care if they did know, that the Bible teaches that human beings, not animals, are created in God's image.
So, too, those who cannot call any abortion immoral are moved by what they see -- the forlorn woman who wants an abortion, not by the human fetus they do not see. That is why abortion rights groups are so opposed to showing photos of fetuses that have been aborted -- such pictures might move the eye and the heart of viewers to judge the morality of many abortions differently.
It is undeniable that many people have used their minds and many have used the Bible in ways that have led to evil. And some of these people have been truly heartless. But not one of the great cruelties of the 20th century -- the Gulag, Auschwitz, Cambodia, North Korea, Mao's Cultural Revolution -- came from those who took their values from the Bible. And the great evil of the 21st century, though religion-based, doesn't come from the Bible either.
Meanwhile, the combination of mind, Judeo-Christian values and heart has produced over centuries the unique success known as America. Reliance on the heart will destroy this painstaking achievement in a generation.
