I believe that abortion is definitely wrong. However, I have wondered at what should be done in the situation where a child was pregnant and their pregnancy would be extremely likely to put their life at risk. In a perfect world this would never happen, but unfortunately we live in a world where tragic things could happen, so I think we should be prepared for these kinds of scenarios. I would hope that there could be some way medically other than abortion to preserve the child's life, but if not, what should be done?
It is not that I think abortion in ANY scenario - even in a scenario where a young child's life is at risk - is a good thing at all, but would the life of a newborn baby be worth the death of a young child (though I think that the death of the fetus would also be tragic)?
I do not think that an adult mother's life being at risk due to pregnancy justifies abortion, however I think if one were in such a situation it might be much more difficult emotionally and/or to process than if one were just hypothetically imagining the situation. Also, women in this scenario may not necessarily be Christian which could make the issue a bit more difficult. I am not sure but I think nowadays it is rare that pregnancy would definitely result in a mother's death even with medical treatment.
Though I understand that some situations may be much more traumatic and/or difficult than others, I believe abortion can never be justified in any other scenario, such as rape, likelihood of babies being born with serious deformity or life-threatening complications, or limited resources to care for the newborn baby. I think that ideally there should be community support provided for mothers and babies in difficult situations, and I believe that the needs of mothers in traumatic situations (e.g. rape, teenagers or children giving birth) must be attended to and not neglected.
I believe that God can work miracles and preserve the life of the mother and/or baby against all medical odds if He wills.
