And the most beautiful part about this process is that although a man and woman “make” the baby, God is responsible for “making” the soul and infusing it into the embryo.
This is all in perfect unison with the universal teaching that God was the creator, and creation is the act of making something from nothing. Before the sperm and egg unite to form a baby, the soul for that child does not exist. The exact moment the child is “made”, God makes and infuses the soul at that same moment.
Of course, souls are not just “sitting around” waiting to be placed into embryos. That would be akin to treating souls as the eggs in a woman’s ovaries. A certain number of eggs are formed at the appropriate time during a female’s development as a person, the eggs do not (as an almost universal proposition) increase in number as the female ages, and the eggs are released, on average, once per “cycle”.
Thus, yet another mystery of God: knowing the identity of, through the power of omniscience, all babies and souls before the babies are made, but not yet creating the souls until the babies are made.
