Concealment does not block observation by our Creator. In this regard David said: “For you yourself produced my kidneys; you kept me screened off in the belly of my mother. I shall laud you because in a fear-inspiring way I am wonderfully made. Your works are wonderful, as my soul is very well aware. My bones were not hidden from you when I was made in secret, when I was woven in the lowest parts of the earth. Your eyes saw even the embryo of me, and in your book all its parts were down in writing, as regards the days when they [the body parts] were formed and there was not yet one [distinct body part] among them.”​—Psalm 139:13-16.

Before David’s body parts became distinct in his mother’s womb, his appearance was known to God. Why? Because the development of the embryo followed a specific pattern, as though obeying instructions recorded in a book. How this shows Jehovah’s wisdom and ability to see even concealed things! It should also make us appreciate that God created the human race and is responsible for the wonderful reproductive process that has resulted in our existence as individuals.
