What does the analogy of the fetus in the womb show about how precisely the body's cell-making process works?
The analogy shows the body's cell-making process is extraordinarily precise: cells are placed exactly where needed so the fetus develops complete fingers, fingernails, and eyes. It rarely makes mistakes such as an overly long finger or toe, and the process stops at just the right time, followed by delivery.
Les uses the analogy of the fetus in the womb, drawing from an article by a physiologist or embryologist. At the beginning of pregnancy, the mother's body immediately begins to put all different kinds of cells into exactly the right place. By the end of the nine-month period, the little fetus has all his fingers and fingernails, the eyes, and everything complete. As the author pointed out, the body rarely makes a mistake by making one finger much longer than it should be, or making toes longer; instead, everything stops its cell-making process at just exactly the right time. When it is all completed and the baby is finally complete, the cell-making process stops, and then delivery follows. Les then says the church is the same way, as God has been adding individual believers from all around the world.
