How many times have you heard expectant couples say, "Well, as long as our baby is healthy"? John Knight from Desiring God ministries cautions, "'Healthy' exists on a spectrum of possibilities just like disability. And that spectrum is becoming narrower with every passing year." He points to an article about University of Washington scientists who were able to identify the DNA sequence of a fetus with 98 percent accuracy, and with safer techniques.

The article noted, "The accomplishment heralds an era in which parents might find it easier to know the complete DNA blueprint of a child months before it is born. That would allow thousands of genetic diseases to be detected prenatally." That means that more children with disabilities will be aborted.

But Knight also argues that many people will be tempted to order up "designer babies"—all fueled by "an increasingly idolatrous mindset that says I have the right and the responsibility to determine what is best for me — including the physical and/or developmental makeup of my children, or somebody else's children."
