The sixth commandment, "You shall not murder" (Exodus 20:13), covers the grievous sins of abortion and after-birth abortion (infanticide) quite adequately once we accept that the newborn child is certainly a living human being—and has been for many months. While the Bible contains no direct statement that life begins at conception, many passages show that God is involved in people's lives before they are born (see Psalm 139:13-16; 51:5; Isaiah 49:5; Jeremiah 1:4-5) and that the fetus is aware and responsive to God (Luke 1:41, 44). God even commands life for life if a fetus is miscarried after a fight (Exodus 21:22-24). The weight of biblical evidence falls on the side of life and full humanity for fetuses and newborns.
Actually, this brave new world of abortion and infanticide on demand is simply the modern equivalent of ancient pagan practices like the abhorrent idolatry of the Canaanites in Old Testament times. Pagans would sacrifice their children to their gods to "ensure" the living would have better lives. They would make a child "pass through the fire to Molech" (an act obviously forbidden by God; Leviticus 18:21) to supplicate the god to give them fertile fields, victory in battle, or some other blessing. Ironically, these ancient people held the life of a child as dearer than today's uber-selfish individuals do, as the latter most often abort babies merely for their own convenience.
Concerning this horrible sin, God says of the people of Judah in Jeremiah 32:35:
And they built the high places of Baal which are in the Valley of the Son of Hinnom, to cause their sons and their daughters to pass through the fire to Molech, which I did not command them, nor did it come into My mind that they should do this abomination, to cause Judah to sin.
As punishment, Jerusalem was "delivered into the hand of the king of Babylon by the sword, by the famine, and by the pestilence" (Jeremiah 32:36). When such practices become commonplace, the society is ripe for destruction, as God intimates in Genesis 15:16 and Leviticus 18:24-29; 20:22-23. There is nothing ethical about "potential persons" and "after-birth abortion." They are the products of the twisted thinking of human beings tuned in to the broadcasts of a hateful Satan the Devil (Ephesians 2:2-3). He wants to destroy human life. Hundreds of millions of abortions are not enough to sate his appetite, so he has deceived people into taking the next step toward annihilation, infanticide. Could there be any better reason to increase our prayers to God to send His Son soon?
