I'm not an expert on Scripture but I do believe when we see children being killed we have an obligation to try to save them.
If you saw a child drowning in a river, would you rely on Scripture for guidance or just try to save him?
But, to answer your question, did you know that a tower collapsed in a town where Jesus taught and He did nothing to stop it? Or that he did not heal every sick person in a town? There was a method to Jesus's operations, guided by scripture, and it certainly would not have involved carrying a jar with a fetus in it.
