The expression "Pro-Life" is at the heart of the issue regarding the legality of abortion. The Pro-Lifers usually oppose all forms of Induced Abortion - Elective Abortion as well as Therapeutic Abortion. They believe that the life of a human being starts at conception, and also that every phase of this life, right from the embryo to the fetus and finally to the newborn, is entitled to live.

Anti abortionists are of the opinion that far more development and transformation of the physical features takes place in the gestational phase prior to birth than happens during the entire period of an individual's life.

In fact, well inside the initial three weeks, the basic biological structure for the nervous system, brain, and the spinal cord start developing and the heart takes on a beat. In the following couple of weeks, a baby develops lungs, limbs, musculature, eyes, and in due course starts to stir. Five months into the pregnancy, the mother experiences a baby's kick; by six months, a baby is able to hear; and at seven months, a baby opens its eyes and is able to see. Pro-Lifers are also not in favor of abortion since they imagine that a baby can feel the pain.

In addition to all the development and transformation stated earlier, Pro-lifers think that the baby also develops a consciousness and a soul that would be wiped out by an abortion. The subject of the soul's existence is regularly spoken about by people who oppose abortion. A great number of Pro-Lifers have faith in God and believe that a person's soul is created at the time of conception.

The anti abortionists, who are Christians by faith, think that the Bible underscores their viewpoint against abortion. Now, Christians avail of Bible verses to form logic behind their convictions. For instance, the Bible teaches that innocent life should not be taken (Genesis 9:6, Exodus 20:13, Deuteronomy 27:25a, Proverbs 6:16-19).

Several people declare that the Bible maintains that yet to be born babies represent human life in the books such as Genesis and Luke. Besides, the books of Jeremiah and Luke pronounce that God knows the soul of a person prior to their being born. Hence, an unborn baby ought to be human life since God knows the baby, and by taking away a human life, you are going against God's will.

Pro-Lifers are opposed to abortion even if incest or rape is involved. Though they are of the opinion that these are abominable and appalling offenses and the persons responsible for these vile acts should be severely dealt with, they also believe that unborn children produced by these unpardonable sins should not, in any way, be penalized. These children are blameless consequences of sexual misdeeds.

Pro-Lifers assert that abortions should not be financed or supported in any form by the government. Now, this encompasses the financial support extended to clinics such as Planned Parenthood. Anti abortionists, at times, perpetrate brutal acts of hostility directed at abortion clinics. There have been cases where the lives of abortion doctors were taken, and clinics razed to the ground by zealous Pro-Lifers. A majority of Pro-Lifers state that there is no justification for these mindless killings to put a stop to abortions.
