Conception is not fertilization.
John 3
6.*"That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
Conception has something to do with God’s Will and God’s Plan for our salvation and Our Freewill to cooperate with God’s Plan. Humanity is the “female” partner of God’s plan for Salvation.
Conception is found in the bible in Genesis 1:1, and John1:1-14. There are conception for the heaven and earth as well as conception of each of new person.
I agree that we are not mere dna, because we are also spiritual beings. In fact our biological body is a mere temporal vessel for the spirit of God in us.
The bible also write that God has planned our life since the foundation of the earth. Thus life has begun since then, even before we were in our mother’s wombs.
Jeremiah 1
5.*“Before I formed you in the womb I knew you,
And before you were born I consecrated you; …”
God’s love is what drive conception including in the way humanity cooperate, therefore I would argue that “a motherly instinct” is part of conception. In Isiah 66:9 is said:
Isiah 66
9.* “Shall I bring to the point of birth and not give delivery?” says the LORD.
“Or shall I who gives delivery shut the womb?” says your God.
10.* “Be joyful with Jerusalem and rejoice for her, all you who love her;
Be exceedingly glad with her, all you who mourn over her,
11.* That you may nurse and be satisfied with her comforting breasts,
That you may suck and be delighted with her bountiful bosom.”
12.* For thus says the LORD, "Behold, I extend peace to her like a river,
And the glory of the nations like an overflowing stream;
And you will be nursed, you will be carried on the hip and fondled on the knees.
13.* “As one whom his mother comforts, so I will comfort you;
And you will be comforted in Jerusalem.”
14.* Then you will see this, and your heart will be glad,
And your bones will flourish like the new grass;
And the hand of the LORD will be made known to His servants,
But He will be indignant toward His enemies.
15.* For behold, the LORD will come in fire
And His chariots like the whirlwind,
To render His anger with fury,
And His rebuke with flames of fire.
16.* For the LORD will execute judgment by fire
And by His sword on all flesh,
And those slain by the LORD will be many.
17.* “Those who sanctify and purify themselves to go to the gardens,
Following one in the center,
Who eat swine’s flesh, detestable things and mice,
will come to an end altogether,” declares the LORD.
However, what is consisted within “God’s love that nurse the child” is not necessarily only the love of the “birth mother”. It also can mean the love of adoptive parents, and even care-giver at the orphanage, grandparents, and biological father too.
The passage choose the word “nurse” to depict the imporance of a motherly love for the newborn child (the child=Israel, plase read Isiah 46:3), and in contrast, such “nursing love” is not present for God’s enemies (Isiah 66:14-17).
Humanity cooperation to God’s salvation is the question. Our permissive culture goes against God’s plan. God doesn’t will adultery. However, **God’s saving grace can’t be defeated by our sins when a child is born despite the parent’s sins, not by coercion. **
Please read also Job3:11, 10:18-19, 24:20, 31:15-18, 38:8-29; Isiah49:15, 44:24, 46:3, and there are many more verses regarding conception/ the birth of Israel/ God’s foundation of salvation, and so on.
Isiah particularly speaks about God’s plan for salvation in the mixed prophesy about the birth of Christ and Judah’s war with God’s enemies (the nations who practice abominations). Please Read Isiah 7.
Isiah 7
1.* Now it came about in the days of Ahaz, … king of Judah, that Rezin the king of Aram and Pekah the son of Remaliah, king of Israel, went up to Jerusalem to wage war against it, but could not conquer it.
2.* When it was reported to the house of David, saying, “The Arameans have camped in Ephraim,” his heart and the hearts of his people shook as the trees of the forest shake with the wind.
3.* Then the LORD said to Isaiah, "Go out now to meet Ahaz,…
14.* "Therefore the Lord Himself will give you a sign: Behold, a virgin will be with child and bear a son, and she will call His name Immanuel.
I write all of the above not in order to defend abortion, but to make a point that abortion is an outcome of adultery and abomination according to the bible.
Since conception and fertilization are different but not separate, I agree that we as humans (and not Gods) should not decide whether a biological life of fetus can be terminated. Instead we should try to save it if we can. The question is how? Shall we declare Adultery Illegal? Shall we arrest those who commit adultery? In South Korea and many other parts of the world, adultery has been crime until recently.
