Biblically, life definitely begins at conception. King David said he was sinful from the time he was conceived ( Psalm 51:5). Therefore, he became a person at the moment of conception, for only a person can have a sin nature.
Many scriptures speak of fetuses as children and persons. As soon as she conceives, a woman is “with child.” God sometimes relates intimately with the fetus. (See: Psalm 119:73; 139:13-16; Jeremiah 1:5; Job 10:8-12; 31:13-15; Genesis 25:22; Hosea 12:2-3; Matthew 1:18-20; etc.) God sometimes even prepares them for a specific calling ( Rom. 9:11; Judges 13:3-5; Jer. 1:5; Gal. 1:15).
John the Baptist responded in the womb to the presence of Jesus, who was newly conceived in the womb of Mary ( Luke 1:39-44).
When did Jesus Christ leave Heaven, come to Earth andbecome flesh( John 1:14)?Biblically and doctrinally, it was clearly the moment that He was conceived in Mary by the Holy Spirit.
Human’s have an intrinsic worth because our ancestors, Adam and Eve, were created in the image of God ( Genesis 1:27).
The Bible prohibits the killing of innocent people ( Deu. 19:10). “Thou shall not murder” (Exodus 20:13, NKJV; Genesis 9:5).
Biblically and historically, it is certain that the Israelites knew that the fetus was a child (a person).
In Old Testament Israel, a criminal injury that caused a pregnant woman’s unborn child to die was treated the same as any other murder. The criminal was punished less severely, only if the baby was born alive, although premature( Exodus 21:22-25, NKJV).
“These six things the LORD hates, Yes, seven are an abomination to Him: A proud look, A lying tongue,Hands that shed innocent blood…” ( Prov. 6:16-17, NKJV).
What did early church writings say about abortion?
“You shall love your neighbor more than your own life. You shall not slay a child by abortion. You shall not kill that which has already been generated” (Epistle of Barnabas19.5; second century).
“Do not murder a child by abortion or kill a new-born infant” (The Didache2.2; second century catechism for young Christian converts).
“The fetus in the womb is a living being and therefore the object of God’s care” (Athenagoras,A Plea for the Christians, 35.6; 177 A.D.).
Equality- “ Jesus Christbroke through the false barriers that separated Jewsfrom Samaritans, lepersfrom the healthy, children from adults, wanted from unwanted. He taught the equal dignity of all. The barrier that divides born from unborn is likewise offensive to His teaching.”
Justice- “God saves the helpless, who cannot save themselves. This God of justice expects His people to do likewise, rescuing the orphan and the widow, and intervening to prevent bloodshed.”
This is also answered in Genesis. Genesis 1:26-29and 2:7-23 make it clear that man was created distinct from the animals,made in God’s image. In Genesis 3 we read how this image was corrupted by the sin of the first humans, Adam and Eve. Only one generation later, Cain committed the firstmurder, a destruction of this image, thus a grievous affront to God. Violence (and other evils) spread throughout the world, so God destroyed all people apart from the Ark’s passengers with a globe-covering flood ( Genesis 6-8).
Right throughout Scripture, murder—that is the intentional killing of innocent humans—is regarded as a heinous sin ( Exodus 20:13, Matthew 19:18, Romans 13:9). Since abortion kills an innocent human being, it is nothing less than murder. So all the usual “hard cases” pushed by pro-abortionists, e.g. “ What if the woman was raped?,” “ What if the child is deformed?,” “ What if she can’t afford to keep the child?” are irrelevant.
We should also remember Ezekiel18:20, which prohibits executing a child for the crime of his/her father. This means that even the tragic cases of pregnancies due to incest or rape are no justification for killing the innocent child conceived.
