The surprising thing here is that God beforehand (in the womb already!) knew all the days of my life. He wrote them down, so to speak, in his book. No man can do a thing like this.
We can only jot down the facts of a certain day, after it has happened. Again, we are in awe of an almighty and all-knowing God.
16 Quand je n'étais qu'une masse informe, tes yeux me voyaient;Et sur ton livre étaient tous inscritsLes jours qui m'étaient destinés,Avant qu'aucun d'eux existe.
