Even if there was a case in which this might happen - the murder of the child would be grossly immoral and this practice sanctioned by the state would reveal a satanic control of affairs.
A mother should never kill her babies. No exceptions. Thousands of mothers have died rather than allow their child to be killed by its enemies. To do so as an act sanctioned by the State leaves one aghast.
Abortion is not even biblically permissible in so-called life of the mother cases. We should not follow situational ethics, or the advice of the medical community, personal opinion, to make life and death decisions concerning our unborn children.
“can you name an instance where abortion would save a mothers life?”
The reason I said that is because some people use it as a talking point, and I was trying to show that it is a weak talking point.
