In a tiny book written in German and entitled "Wunder der Schöpfung" (Miracle of Nature) the author writes: "friend, your body is made up of 100 trillion cells. If you attempted to count them, taking a second to count each cell, it would take you three million years. This would not be an easy task because the cells are so tiny; each having an average diameter of 10 micrometers (one micrometer is equivalent to one millionth of a meter or 1/1000 of a millimeter). Yet each of these cells has a definite function in the entire organism: for the construction of the eyes and ears, of the teeth and fingernails, of the brain and hormones... Friend, who made this marvelous body of yours?
In contemplation of God's marvelous work of our beings and the beings of other living creatures, we can only exclaim with Psalm 139:13-14 "You formed my inmost being; you knit me in my mother's womb. I praise you, so wonderfully you made me; wonderful are your works!"
