"You made all the delicate, inner parts of my body and knit me together in my mother’s womb. Thank You for making me so wonderfully complex! Your workmanship is marvelous -- how well I know it. You watched me as I was being formed in utter seclusion, as I was woven together in the dark of the womb." (Psalm 139:13-15 NLT)
Twenty-eight thousand pounds at birth! That's what Dr. Bernard Nathanson estimates we would weigh if we continued to grow throughout gestation at the rate we grow in the first two weeks of life. That's how steep the trajectory of cell division is.
Add to this biological tumult the unimaginably intricate and precise processes of organization that take place during this time, and the picture is breathtaking. Everything from the ability to hit a baseball to the swirl of cowlicks to the sound of a person's laugh are fixed into place. In magnitude, the change is comparable to a tsunami; in complexity, to the transformation of winter into spring. The first two weeks of life may be the most important.
But the real glory and mystery of it all is that it takes place on a scale that is microscopic. The grandest, most awesome stage of human life is, for all practical purposes, invisible.
