All of which is to say that as I sit at the table in the kitchen of my parents’ house in Arizona, and look out through the windows and the open door in the direction of a landscape that in places is untouched, I recognize in myself a feeling of sadness and regret, for a purity that, over time, has been lost or wasted, due to my susceptibility to sin. And yet I do not despair, because in my faith I find the means by which this susceptibility can be redressed, and my purity restored, to an extent.
