Psalm 139: Thinking Theologically, Thinking Scientifically (Part 3)

In Part 1 of this series, we worked through Psalm 139 in its entirety to follow and understand the flow and contours of the psalmist’s theology and prayers. In Part 2, we explored verses 13-16 in more depth to unpack the psalmist’s theology of his own development in the womb, as well as ways in which these verses might assist devout readers in thinking maturely about scientific perspectives on, and discoveries about, a human’s origins and development.

For this post, I am delighted and honored to share with you a guest article by a friend of mine, and a neonatal nurse practitioner, Sarah Bylsma. Sarah shares with us her perspective on Psalm 139:13-16, a perspective that occurs for her at the intersection of her Christian faith, her scientific training, and her professional involvement in caring for newborns, including experience working in a Neonatal Intensive Care Unit (NICU). Sarah, I welcome your voice here, and at this moment offer you my sincerest thanks.


“Faith and Science in Neonatal Practice: A Reflection on Psalm 139”
By Sarah Bylsma

First, a little about me. I graduated with a B.A. in Biology from Lipscomb University in May 2005. I then went to Belmont University and graduated with a B.S. in Nursing in December 2006. In January 2007, I began working as a nurse in a Level III Neonatal Intensive Care Unit. While working full time as a nurse in the NICU, I attended graduate school at the University of Alabama Birmingham from 2009 to 2011. I obtained a M.S. in Nursing with a Neonatal specialty in May 2011. I have been board certified as a neonatal nurse practitioner since September 2011. I currently work full time as a neonatal nurse practitioner. I am also a full-time mom to three little ones ages 5 and under. I have been a Christian since 1990, with evolving beliefs as my worldview has changed, but never questioning the existence of our God.

As I read Psalms 139, the author seems to insinuate three things in verses 13-16: (1) that God is creator, (2) that life begins in utero, and (3) that God knew every detail of that life the moment it began.

I believe that God is creator of all things. My education and experience have shaped HOW I view God as creator, but they most certainly do not change the fact that He is behind the existence of all life.

As a scientist and medical professional, I know that human life forms from two human cells, the egg from the mother and the sperm from the father. Once the egg is fertilized by a single sperm cell, a zygote is formed. The zygote will undergo mitosis, a process a cell undergoes to form two new cells. DNA, our unique genetic code, is replicated in this process. It is here in mitosis, as the zygote grows and divides to become an embryo, that the development of human life can first go awry. Errors during mitosis can result in chromosomal errors ranging from too many / not enough chromosomes to extra / missing pieces of chromosomes — all of which can create a wide variety of syndromes, cancers, and death.

Often, when embryos are created from cells with abnormal chromosomes incompatible with life, a mother will miscarry. This raises a question about life and its beginning. Is an embryo with genetic information incompatible with an earthly life still a life? Conception had occurred and genetic information exists, but no life will be formed. With my scientific knowledge, I believe that life begins in utero, but not at conception. My reading of Psalm 139 does not dispute this. The author understands that life began in his mother’s womb, and the scripture does not explicitly state a time-frame. I believe you would be hard-pressed to find anyone working in neonatology that would dispute that life begins in utero.

God knowing every detail of each life the moment it begins is different than God choosing every detail for that life. This is because God gives us choices (free will). You may be asking questions like: How does that play into embryologic development? What about when the formation of life goes wrong? If God is creator, how can that go wrong? No one chooses how our babies are formed in utero, right?

God has given us free will, and that freedom to make our own choices can and does affect others. This includes the developing fetus. Sometimes these can have devastating effects on the fetus. As Daniel pointed out in Part 2, the psalmist clearly understood that the mother and father played a role in the human-making process. Their role is not just one of providing the cells to be fertilized, but also to create an environment in which proper development can occur. The psalmist describes being knit together in his mother’s womb. Choices help determine the kind of knitting that occurs.

Daniel has already discussed how the materials used in the knitting process affect the end result. Embryonic development and postnatal health is most certainly affected by the parents’ individual choices and environmental factors both before and while the mother is pregnant. Choices from our past can impact our bodies or the environment, which in turn impact embryonic development. The mother and father’s choices (both before and during pregnancy) on lifestyle, nutrition, drug use, sexual activity, etc., can alter fetal development. For example, sexually-transmitted diseases, particularly when acquired during pregnancy, can be especially harmful to a developing fetus.

It’s clear that bad choices can have an effect on development. But there are other choices that can impact it also, such as age at conception: older mothers have a higher chance of chromosomal errors. Sometimes we do not know why something goes wrong in the development process. There are many intricate steps involved in creating a human life, and thus many places for the process to go wrong. Research has shown us that unknown diseases, illness, hormones, and genetics can all impact a growing fetus. Despite all of the scientific advances, sometimes we do not know why the process goes amiss. Sometimes the process is going normally but gets interrupted, resulting in premature birth.

So we know that embryological development can go wrong, regardless of how it goes wrong. In my line of work, I see so many ways in which the development went awry or was interrupted. I don’t always know how it happened or why. It is our tendency to see these as abnormalities and imperfections, something to be feared and less-than-desired. How can God create a life like that? But I see God in these babies the most. I watch these babies grow and mature, and I know their lives still have purpose and meaning. I see God in that baby who is missing parts of his brain, who can still walk and talk and amaze healthcare professionals with his progress. I see God in that premature baby born 4 months too soon, who through medical advancement and technology is able to grow and develop into a perfectly healthy infant.

Occasionally I see babies that do survive but have severe lifelong and debilitating complications. Why does God allow these babies to survive? WE see these as imperfections, but to our God they are perfect, just like the rest of us. Their lives have purpose, even when we fail to see what that is. We are all fearfully and wonderfully made in God’s eyes.

Often I see these babies live and thrive, but sometimes, they don’t make it. Sometimes, they are simply born too early. Sometimes, their development was affected so greatly that life outside the womb isn’t possible. The complexities of human development sometimes allow life to persist in utero, but not after birth. Why does God allow these lives to exist throughout the duration of a pregnancy, but not long enough to have a life on earth? I have struggled with this question. I have shed many tears over the losses of a life gone too soon. I do not have the answers. Even while writing this, I have spent hours and hours thinking about it, trying to come up with an answer. Science can answer many questions about life, but sometimes…often…you just need to have faith and know that our God has a plan, even when we do not understand it.
