First of all, abortion addresses a fetus, an incomplete non-living being. One cannot take the life of something that has never been alive.
A fetus is just a bunch of parts being manufactured and assembled. God is very specific as to when a fetus becomes a living being: “The LORD God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being” (Genesis 2:7). Adam did not become a living being until then. God breathed into the nostrils of man his spirit, which who a person really is. The body dies and returns to dust, while the spirit lives on forever.
I am not sure why you would apply the scripture about clay and man being formed from clay when the clay has no limbs, no pumping blood and no umbilical cord attachment to someone living so they can live and grow. The clay once formed and given the breath of life starts the circulation as well as the breathing.
Also the scripture knowing someone before they were even formed in the womb testifies to the soul in that womb, regardless of that soul not being born yet.
Fetus is a term used by that false science the evolution theory, which the political arena took to give rights to "fornicators" to murder the unwanted unborn. So the unborn child is more than a fetus and more than a lump of clay. If you read this again with His help... you'd think differently.
Psalm 139:13 For thou hast possessed my reins: thou hast covered me in my mother's womb. 14 I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. 15 My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth. 16 Thine eyes did see my substance, yet being unperfect; and
in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them. 17 How precious also are thy thoughts unto me, O God! how great is the sum of them!
I cannot see how the members of the unborn written in His book when there has not been none of them, cannot infer that the aborted unborn is written in His book. Since children are a reward from the Lord, the fruit of the womb is the reward, then killing that reward before that child is born ought to be an offense to God.
So let us research; is there any scripture that testify to a soul in the womb before birth that one wishes to give his soul while in the womb and even after birth? Yes.
Job 3:11Why died I not from the womb? why did I not give up the ghost when I came out of the belly?
Did any prophet testify that he existed in the womb that wished He had slew him before he was born? Yes.
Jeremiah 20:17 Because he slew me not from the womb; or that my mother might have been my grave, and her womb to be always great with me. 18 Wherefore came I forth out of the womb to see labour and sorrow, that my days should be consumed with shame?
So there are indication that the soul of the unborn exists and you can't say because the breath of life was not in that unborn child because that unborn child is breathing in another way.
How Do Babies Breathe in the Womb?
"Since a baby developing in the womb lacks the ability to breathe, the mother's body must accomplish the
exchange of oxygen and carbon dioxide. In essence, the mother breathes for the baby before birth. Just as an expectant mom is eating for two, she is also breathing for two.
The exchange of gases occurs in the
placenta, the organ that develops within the uterus during pregnancy to sustain the developing baby. Although the baby and mother have separate bloodstreams, the placenta serves as an interface where gases as well as nutrients can pass between them.
When an expectant mom inhales and takes in oxygen, her circulatory system delivers some of it to the baby's bloodstream through the placenta and umbilical cord. The baby's circulation rids itself of excess carbon dioxide when it passes into the mother's bloodstream via the placenta. The mother's lungs expel carbon dioxide from both the baby's body and her own when she exhales."
So an unborn child is hardly clay, let alone a clinical scientific term called fetus to disregard it as a soul living child not yet born..
