In "God's Word for Today" Gordon Snider writes:
Ever since the publishing of Charles Darwin's On the Origin of the Species in 1859, there has been an increasing tendency to treat people with less dignity than God intended. The problem is widespread in our society. Many of the ethical questions facing today's world — genetic engineering, abortion, and assisted suicide, to name a few — are the result of this tendency to treat people as things to be manipulated rather than beings to be honored and respected. Sadly, even Christians who take strong, biblical stands on these issues can fall prey to the same subtle temptation. Often, perhaps always, when we fail to show due consideration for others, we have yielded to the temptation to treat others as something less than human. When we use people to accomplish our goals, we have done the same. Abuse in almost any form begins with denying the God-given dignity of the other person.
