Another insight from today's Biotech Century Conference: Christians can use biotech issues to build common ground with some (perhaps) unlikely allies. For example, some feminists oppose human cloning because of its impact on a woman's health. Environmentalists are concerned about the unrestricted "progress" of the biotech industry because of irreversible effects on ecosystems and because biotechnology misdiagnoses the problems it is attempting to solve.
The beauty here is that Christians can agree not only that certain biotechnologies are harmful and wrong, but we can also agree even with many of the reasons these folks oppose them (for we certainly should be just as concerned about women's health and the environment as these folks are) and make common cause with them. The common ground we build gives us an opportunity to share our more fundamental reasons to be concerned (e.g. cloning creates human beings in order to kill them for research). While they may disagree with our reasons, our willingness to listen and affirm them will create a context where many of the barriers to hearing Christ's view are removed.
Being an ambassador is not just about knowledge and having a grasp of all the reasons something is wrong. We also must have an intellectually honest character, more in love with the truth than with rejecting people based on group affiliation. If they make a good point, let's affirm it.
