The man must never have known a longer hour. Hope is a thorn in the side of doubt, not a thing with feathers that perches in the soul. It aches. And at the end of it all he does —you will—still fail. Peter denies Christ again. The rooster crows, and Jesus looks at Peter, because even though Peter has denied Jesus, Jesus has not denied him. His opportunities are not yet exhausted.
The majority of us — who Augustine called the non-valde-boni, the not-very-good-ones—live our whole lives in the space of that hour. We hope. We try. We will probably fail. It will happen over and over again. The most relatable Christians in literature are not the subjects of hagiographies, but of the kind of morally ambiguous stories that amount, in the end, to what we call a life. Shusaku Endo’s Kichijiro, who repents only one more time than he apostatizes, is perhaps the ideal form.
In an era where solutions are judged by their efficiency, it can be hard to accept that this is just how grace works on fallen creatures: like a spiral, circling around you over and over again as you repeat the same mistakes, drawing nearer and nearer to your heart the longer you seek it. It isn’t that grace is ineffective or inefficient but that we are, being what we are, imperfect vessels for it. The miracle is that it works anyway
