Psalm 139 is the most quoted pro-life Bible verse, but I think that the New Testament is more convincing than all the rest for the abortion-minded.
Most Sanctity of Life sermons focus on Psalm 139, written by King David. The key verses say:
For You formed my inward parts;
You wove me in my mother’s womb.
I will give thanks to You, for I am fearfully and wonderfully made;
Wonderful are Your works,
And my soul knows it very well.
My frame was not hidden from You,
When I was made in secret,
And skillfully wrought in the depths of the earth;
Your eyes have seen my unformed substance;
And in Your book were all written
The days that were ordained for me,
When as yet there was not one of them.
(Psalm 139:13-16 NASB)
David was a gifted writer and clearly inspired by the Holy Spirit. As believers, we understand that his Psalms were written for him, for the kingdom of Israel, and for us.
However, abortion-minded women and non-believers may say that David was different because God chose him to be king, that David had a special calling on his life and therefore the verses don’t apply to the unwanted pre-born.
David also said these words:
"Upon You I was cast from birth;
You have been my God from my mother’s womb."
(Psalm 22:10 NASB)
Jeremiah was also known by the Lord before he was born:
“Before I formed you in the womb I knew you,
And before you were born I consecrated you"
(Jeremiah 1:5a NASB)
Job recognizes that God made him in the womb:
“Did not He who made me in the womb make him,
And the same one fashion us in the womb?"
(Job 31:15 NASB)
Jacob and Esau, twins, were known in the womb and referenced by Hosea and Paul.
The children (Jacob and Esau) struggled together within her, and she said,
“If it is thus, why is this happening to me?”
So she went to inquire of the Lord. (Genesis 25:22 ESV)
In the womb he (Jacob) took his brother by the heel (Hosea 12:3a NASB).
And not only this, but there was Rebekah also,
when she had conceived twins by one man, our father Isaac;
for though the twins (Jacob and Esau) were not yet born
and had not done anything good or bad,
so that God’s purpose according to His choice would stand,
not because of works but because of Him who calls (Romans 9:10-11 NASB).
Sampson knew that God recognized him before he was borne:
And he told her all his heart, and said to her,
“A razor has never come upon my head,
for I have been a Nazirite to God from my mother's womb.
If my head is shaved, then my strength will leave me,
and I shall become weak and be like any other man.”
(Judges 16:17 ESV)
Christ spoke these words through Isaiah:
Listen to Me, O islands,
And pay attention, you peoples from afar.
The Lord called Me from the womb;
From the body of My mother He named Me.
(Isaiah 49:1 NASB)
And now says the Lord, who formed Me from the womb to be His Servant,
To bring Jacob back to Him, so that Israel might be gathered to Him
(For I am honored in the sight of the Lord,
And My God is My strength)
(Isaiah 49:5 NASB)
The apostle Paul knew he was formed in the womb:
But when God, who had set me apart even from my mother’s womb
and called me through His grace, was pleased...
(Galatians 1:15 NASB)
Solomon wrote these words:
Behold, children are a heritage from the Lord,
the fruit of the womb a reward.
(Psalm 127:3 ESV)
What may be more convincing is this verse about God knowing all the people of Israel before they were born:
Thus says the Lord, your Redeemer, and the one who formed you from the womb,
“I, the Lord, am the maker of all things,
Stretching out the heavens by Myself
And spreading out the earth all alone.
(Isaiah 44:24 NASB)
If I had heard this verse when I was abortion-minded, I would’ve believed that it applied to me and therefore to my baby. However, I can see that some people may say that the verse only applies to Jews because God was speaking to and about the Jews.
The verses, though, that were most convincing to me require a little knowledge of Greek. Fortunately, we can look up Greek meanings for free using the Blue Letter Bible website.
The New Testament was written in Greek. The Greek word brephos is used to refer to both a pre-born baby (Luke 1:41, 44) and children (Luke 18:15-17). Ironically, Luke was a doctor.
When Elizabeth heard Mary’s greeting,
the baby (brephos) leaped in her womb;
and Elizabeth was filled with the Holy Spirit.
(Luke 1:41, 44 ESV)
And they were bringing even their babies (brephos)
to Him so that He would touch them,
but when the disciples saw it,
they began rebuking them.
But Jesus called for them, saying,
“Permit the children to come to Me,
and do not hinder them,
for the kingdom of God belongs to such as these.
Truly I say to you,
whoever does not receive the kingdom of God like a child
will not enter it at all.”
(Luke 18:15-17 NASB)
I pray that these verses help you convince your Christian sisters and brothers that the Lord has recognized them in the womb as well as all pre-born whether wanted or not.
