Adam Clarke on Psalms 139:14

I am fearfully and wonderfully made - The texture of the human body is the most complicated and curious that can be conceived. It is, indeed, wonderfully made; and it is withal so exquisitely nice and delicate, that the slightest accident may impair or destroy in a moment some of those parts essentially necessary to the continuance of life; therefore, we are fearfully made. And God has done so to show us our frailty, that we should walk with death, keeping life in view; and feel the necessity of depending on the all-wise and continual superintending care and providence of God.
