One of the most powerful essays I have read this year (thus far) is The Hand In The Wound, by Virginia Stem Owens. I am disappointed to have not been able to find it on the Internet, but should you want to read it too, perhaps a local library would prove helpful.
Owens' essay is basically about flesh and the deterioration thereof. It's morbid, and a little bit frightening. Yet, it is also a compelling call to examine the frailty of our earthen shells, and the awesome reality that our Savior came and made Himself like us in our mortality.
Do read it.
