The word of God makes it clear to us that abortion is not a sin. In fact it's quite clear that to believe otherwise is nothing short of idolatry and blasphemy, and those are, quite definitely, sins.
PSALM 139 AND THE BEGINNING OF LIFE
One of the most beautiful chapters in the Bible is Psalms 139. It speaks of God's constant, practically doting, love for his creation. It is distressing to see this chapter used by anti-abortionists as proof that life begins at conception. If you read the chapter in its entirety it becomes clear that our existence begins in the mind of God and that God's attentions follow us all of our days, through good and bad. Here are the verses that anti-abortionists use to twist this beautiful chapter to a common political tool: "For thou hast possessed my reins: thou hast covered me in my mother's womb. I will praise thee; for I am fearfully and wonderfully made: marvelous are thy works: and that my soul knoweth right well. My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth. 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." Psalms 139:13-16.
These verses are used to prove that human life begins at conception. But there is nothing here to even suggest that. God conceives of us first. We read that a blueprint, of sorts, exists in a book, God's book. Before we are born God uses this to form our bodies. Nowhere here does this describe anything but the making of the human form. Nowhere here does it describe how we are imbued with a human soul. But there are numerous other places in the Bible where God makes it quite clear when and how we become a living being and not just an "imperfect substance" as mentioned in Psalms 139.
Consider first, Genesis 2:7,
"And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."
First, God forms Adam, he forms of dust, a flesh and blood body. SECOND, he "breathes into his nostrils the breath of life" and THEN man became a living soul. Man did not become a living soul when God first formed the IDEA of creating Adam, in Genesis 1:26. Man did not become a living soul when God created his BODY. Not until God gave man his first BREATH did he become a living soul. Life comes from God. It does not come from human conception. To believe that the entry of a sperm into an egg constitutes a human soul is blasphemy. To believe this is to eject God from the mystery of birth and put the power of the male ejaculation above the generative power of God. It is nothing less than idolatry, elevating the status of mere man, his sperm and his ejaculation above the power of God to give life.
The verses in Genesis are not the only verses in the Bible to make this clear. Consider Job 33:44
"The Spirit of God hath made me, and the breath of the Almighty hath given me life."
Consider the story of Ezekial and the dry bones, Ezekial 37:1-6,
"The hand of the Lord was upon me, and he brought me out by the Spirit of the Lord, and set me down in the midst of the valley; it was full of bones. And he led me round among them; and behold, there were very many upon the valley; and lo, they were very dry. And he said to me, "Son of man, can these bones live?" And I answered, "O Lord God, thou knowest." Again he said to me, "Prophesy to these bones, and say to them, 'O dry bones, hear the word of the Lord. Thus says the Lord God to these bones: Behold, I will cause BREATH TO ENTER YOU, and you shall live. And I will lay sinews upon you, and will cause flesh to come upon you, and cover you with skin, and PUT BREATH IN YOU, and you shall live; and you shall know that I am the Lord.'"
Just like Adam, who had a body before he had a soul, like every fetus in the womb, these dry bones were given sinew, flesh and skin, and AFTER they received the body GOD breathed into them and THEN they became alive. And, as in the verses above, because of that we "know that [God] is the Lord." Only God can bestow life and he tells us again and again in his word how this is done.
There is no trickery here. God does not breathe through an umbilical cord. We receive the breath of life, from God, through the nostrils, when we take our first breath. The concept of life beginning at birth, rather than conception, is so central to Christianity that we are "born again," not "conceived again."
ABORTION IN THE BIBLE
Why doesn't the Bible say anything directly about abortion? Why didn't Jesus dedicate his crusade against the practice as many of his modern day followers have? Did women have abortions in Biblical times? Yes. The Bible tells us so. Many anti-abortionists feel that the commandment, "Thou shalt not kill," covers the abortion issue. But in Mosaic law God covers the exceptions to this law, indicating quite clearly who may be killed and for what offense. For instance, if a man or woman has sex with an animal or commits adultery they must be killed. Does "Thou shalt not kill" apply to abortion? No. Miscarriage or abortion is an exception. Let's look at Exodus 21:22 "When men strive together, and hurt a woman with child, so that there is a miscarriage, and yet no harm follows, the one who hurt her shall be fined, according as the woman's husband shall lay upon him; and he shall pay as the judges determine."
In this instance a woman has been so injured, in a fight between two men, that she has aborted. The law states that if "no harm follows" the outsider must pay the husband a fine. An abortion has been induced through violence and this is not considered harmful. Abortion, then, is not a capital offense or a violation of the commandment, "Thou shalt not kill."
Does anyone know where in the Bible a prophet of God calls upon God to induce abortions in the wives of his enemies? Let's look at Hosea 9:14.
"Give them, O Lord: what wilt thou give? give them a miscarrying womb (an abortion) and dry breasts."
"...yet will I slay even the beloved fruit of their womb." Hosea 9:16
In this case God causes abortions, the prophet prays that these women will abort. If these are truly innocent children, how could God do this? But they are not, they are "miscarrying wombs," "unperfect substances" and God will prevent them from becoming human souls that will grow up to oppress his people.
WHAT IF MARY HAD DECIDED TO ABORT JESUS?
Many people are surprised to learn that God gave Mary a choice concerning her pregnancy with the future Savior. In the gospel of Luke the angel came to her announcing what the will of God was for her life. In verse 1:38 Mary replies, "Behold the handmaid of the Lord; be it unto me according to thy word." Mary gives her assent. To believe that Mary had no voice in the process is unthinkable, for that would mean that God forced Himself on (raped) an unwed, teenaged virgin. Mary chose to be the mother of our Savior. God honored her ability to make that choice.
Abortion is not a sin, though blasphemy and idolatry are. To say that human copulation (which the Bible calls unclean) has the power to bestow life is blasphemy. No mere act of man can negate the fact that only God bestows life, by giving the fully formed body, breath. Asserting that human life begins at conception is counter to the claims of the word of God and is a sin. It is doubly a sin because this debased belief leads others to sin. Those that kill clinic workers, harass clients and attempt to legislate this wayward belief lead innocent believers down a road to murder and depravity. Follow the example of Jesus, let those that want Christ come to you. Do not force the grace of God on anyone. God has the power, not only to give life, but to save. As Paul says in Galatians 2:21
"I do not frustrate the grace of God : for if righteousness come by the law, then Christ is dead in vain."
