Yes, abortion is wrong. The Lord has said, "You shall not murder," (Exodus 20:13). The life that is growing within the mother is a child, a baby. The Bible looks at the life in the womb as a child.: Exodus 21:22 says, "And if men struggle with each other and strike a woman with child so that she has a miscarriage, yet there is no further injury, he shall surely be fined as the woman's husband may demand of him; and he shall pay as the judges decide,"(1) (NASB).
The main concern of the "Pro-Choicers" is not the guarded protection of the life in the womb. Instead, the main concern is the "rights" of the mother over and against the rights of the child growing in her. The child, who cannot exercise its own will, is killed. And, in order to make the killing more palatable, the baby is called a "fetus", or "non-viable", or "not yet human", etc. This eases the conscience. But, for those who say the baby isn't 'viable', have you ever seen a sonogram of an abortion? You can see the 'non-viable fetus' retracting from the instruments of death and seeking self preservation. It wants to live. Some would respond by saying that even a rodent wants to live. But what is in the womb of the mother is human.
The Bible says for people to protect the weak and down trodden. But with abortionists, the rights of the baby are sacrificed to the rights of the mother -- and the father doesn't even have any rights. The mother cries out that the life in here is part of her body and that she has the right to do with her body as she wills.
True love does not seeks its own, but is other centered. It gives. "For God so loved the world he GAVE his only begotten son..." (John 3:16). Abortion is the ultimate in selfishness. It puts the mother's convenience and desires above the life of her own baby. To kill the baby in the womb means to consider oneself more important than anyone else.
Even in nature, as far as I understand, animals don't kill what is in their own wombs. People are the only ones who kill their young while still unborn. In this society of "self esteem," "personal accomplishments," and "empowerment," true love is losing out and death is winning.
However, there is hope in Jesus. If you've had an abortion, you can be forgiven by the Lord. All you need to do is confess it to the Lord Jesus and ask Him to forgive you. That is what I did years ago when the girl I lived with became pregnant and had an abortion. I was guilty. As a man, the inner turmoil and guilt I felt was horrible. I can't imagine what it would be life for a woman. Nevertheless, the Lord has graciously forgiven me and her. I say this only in the hopes that others would come to find the sweet forgiveness found in Jesus.
Nevertheless, the unbeliever is not convicted by the words of God. So, I've presented what I consider a logical argument against abortion.
