Abortion-choice advocates often disqualify unborn humans from being as valuable as born humans. But it turns out there are only four differences between an unborn and a born human. None of those differences is morally relevant, and therefore they don't disqualify the unborn from being valuable and protected.
This video explains what those four differences are. It was taken last week when I took a three day bioethics class at Biola University. Scott Klusendorf, who worked for us at Stand to Reason, taught on abortion. Here he was teaching on the S.L.E.D. test. If you want to master the pro-life position, this is one concept you can't do without. I teach on this every time I speak on abortion.
