Scott Klusendorf, president of Life Training Institute, author of The Case for Life: Equipping Christians to Engage the Culture and coauthor of Stand for Life: Answering the Call, Making the Case, Saving Lives, writes:
By all means, preach a biblical view of human value. But students in local churches also need to know how to make an essential pro-life argument and convey it to non-Christians. The basic shape of that argument looks like this:
Premise #1: It is wrong to intentionally kill innocent human beings.
Premise #2: Abortion intentionally kills innocent human beings.
Conclusion: Therefore, abortion is morally wrong.
Pro-life advocates defend that argument with science and philosophy.
We argue from science that the unborn are distinct, living, and whole human beings. You didn’t come from an embryo; you once were an embryo.
We argue from philosophy that there is no relevant difference between you the embryo and you the adult that justifies killing you at that earlier stage of development. Differences of size, level of development, environment, and degree of dependency are not good reasons for saying you could be killed then but not now.
Instead of arguing at a fever pitch, Christian students can be taught to ask thoughtful questions aimed at giving people something to think about. Two of my favorites are,
“Do you believe that each and every human being has an equal right to life, or do only some have it based on something none of us share equally?”
“If it’s wrong to hurt people because of skin color or gender, why is it okay to hurt them because they are smaller, less developed, or in a different location?”
The goal of asking is not dominance but thoughtful engagement.
