“We must give thanks for our preservation; that our lives are prolonged and the use of our reason and understanding, our limbs and senses, are continued to us…
It was owing to your good providence that we did not die at birth, and did not come out from the womb and expire; that the knees received us, and the breasts, that we should nurse.
Though before birth we were called rebels, yet by your power we have been borne by you from before our birth and carried from the womb; and you keep our souls among the living and have not let our foot slip.
All our bones shall say, ‘O LORD, who is like you!’ For you keep the bones, and not one of them is broken.
We lay down and sleep, for you, LORD, make us to dwell in safety.
You have commanded your angels concerning us, to guard us in all our ways; to bear us up in their hands, lest we strike our foot against a stone. And they are all ministering spirits, sent out to serve for the good of those who are to inherit salvation.” (Matthew Henry)
