If God commanded Joshua to kill children (and we all accept that He did so) then God does not have an absolute prohibition against infanticide (and all abortion is infanticide).
This does not mean that abortion is always right, but it does mean that abortion is not always wrong.
Ok sure, point taken. So we can then say that when God is dealing out justice as is His role as God that there are times in which He utilizes wars against a nation to carry out His justice. Doing so will involve the death of people of all ages.
However, within the context of an abortion, particularly in the 98.5% of abortions which are permitted by convenience reasons, which are not directed by God, but are decided upon by His creation, against His creation - those instances are immoral and wrong.
Murder requires the killing of another *person*. A fertilized egg, as one example, is not a person.
The distinction between a human being and a human person is a made up distinction. It is entirely arbitrary and subjective. It is fabricated by people for the sole purpose of justifying an action against a human being that would otherwise be considered immoral.
It's interesting because on the one hand fabricating this distinction acknowledges that humans do possess moral worth and value, which is good and true. But on the other hand, it's devastating because if people buy into it, then it justifies a whole slew of immoral behavior against the human that doesn't subjectively qualify as a person.
They are genetically human, but they aren't viable human persons (which is what murder would require), at least up to some point of physical development when practically no one would dispute it and there can and likely should be some debate as to where and under what conditions to draw the line. But when we are simply talking about a fertilized egg or an embryo, no.
Thanks to advancements in science, we now know that a new, unique human being comes into existence at fertilization. This new human being begins a roughly 25 year period of development, briefly beginning inside the mother. At no point during our development are we not a human being. At no point in our development do we not
look like a human being. An adult looks different than a child, just as a child looks different than an embryo. Yet all equally human beings just at different levels of development.
We also know that according to Scripture human beings stand alone as unique creations of God, created in His Image, possessing inherent moral worth and value. We don't grow into this moral worth and value. Our moral worth and value is not based upon how we came into existence, or how old we are, or how developed we are, or anything else that people may want to discriminate against. Our moral worth and value comes to us by way of God.
Therefore, it should be rather obvious to Christians at the very least, that the intentional and purposeful killing of another human being (particularly one who is utterly innocent) is immoral and wrong. This constitutes 98.5% of abortions.
There is nothing anywhere in the bible that discusses abortion, mentions abortion, or gives us any indication of God's opinion of it. Everything we think on the topic comes from us and our own personal or cultural biases, and deciding that it comes from God is an attempt to create him in our own image.
There are a number of things that Scripture doesn't address head-on. However, there are principles established in Scripture that we can utilize to address the morality of practices. The practice of abortion is not a difficult one to address.
1. All human beings are created in the image of God and possess inherent moral worth and value.
2. A new human being comes into existence at fertilization.
3. The intentional killing of an innocent human being who has done nothing wrong is immoral.
4. Unborn human beings have done nothing wrong.
Conclusion: The 98.5% of abortions which are performed for convenience reasons are immoral and wrong.
Also, while Exodus 21 is not about abortion, it does address the moral worth and value of the unborn. And what it says is that if the unborn were to die as the result of a scuffle, then life for life is owed. That is a powerful testimony to the moral worth and value of the unborn in the eyes of God.
