The primary biblical argument for life beginning at conception is found in Psalm 139, where David claims that God is present in the first moments of a person's life, and that He has plans for that life from its first moments: "For you formed my inward parts; you knitted me together in my mother's womb. … Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them" (Psalm 139:13, 16).
Does life begin at conception according to the Bible?
Other verses in the Bible also support the value of unborn life:
Jeremiah 1:5 says, "Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations."
Isaiah 44:24 talks about God as "your Redeemer, who formed you from the womb."
Paul says in Galatians 1:15 that God "had set [him] apart before [he] was born."
Job 33:4 says, "The Spirit of God has made me, and the breath of the Almighty gives me life."
If we believe what the Bible says, we must come to the conclusion that in both physical and spiritual terms, an unborn child is the blueprint for a fully-formed human being.
As an interesting aside, you may not know that light is actually involved in conception. When the sperm meets up with the egg, there is a biochemical reaction that facilitates entry of the DNA from the sperm to join the DNA within the egg. During the fertilization process, photons are released and create a "light-show". At this time, all of the DNA and "messages" that will eventually result in birth are present. Biblically, light and life are often intricately intertwined (see, for example, John 1:1–5; 8:12). How fun that God celebrates the beginning of a new life with a "light-show" in the womb.
