We who defend the sanctity of life sometimes face questions similar to this: “Why do you say abortion is wrong, if babies go to heaven when they die?” That question often has a follow-up: “Aborted children never have a chance to grow up and reject Jesus; thus, by your own reasoning, abortion fills heaven and keeps people out of hell. Isn’t that a good thing?”
…the first reason that we reject the idea of a mercy-motivated abortion is fairly simple: because God said not to kill. Regardless of what else we may think, God told us that killing the innocent is wrong. Period. Just as with a parent-child relationship, the only thing we ultimately need to know is that the Father has said, “No.”
The second reason that abortion cannot be justified as a merciful act is that we are not absolutely sure what happens to those who die before they are born. We have many good reasons to think they’ll be in heaven, but we don’t have explicit biblical proof. So we can’t definitively say that aborting a soul will rescue it from hell. We dare not take such an awful risk with the souls of other people.
