As an atheist, I can tell you no, that doesn't work. They will one, not respect it, two, there is a separation of church and state so your arguments should not be on the grounds of religions. Not to say that some people don't try. However, using scripture is not a strong argument. I mean, if I told you Zeus said yes to all of this stuff would you take me seriously? Well that's how they are going to feel. You need to use things that will get them without being religious. There is a famous scientist who discovered the cause of both down's and Cru de Chat's syndrome named Jérôme Lejeune and he made some arguments against abortion based on science. You might want to look him up. Anyways, hope this helped.
