When I left Terradillos de Los Templarios before sunrise this morning, the fog was thick. Even with my headlamp on the strongest setting, I could not see more than a few feet in front of me.
The first line that came to mind was “we walk by faith, not by sight.”
And then I thought of the Merton prayer I love so much, praying it as best as I could from memory.
I looked the prayer up when I arrived here in Calzadilla, where I will spend the night. Here it is in its entirety; it strikes me as a wonderful Camino prayer.
My Lord God, I have no idea where I am going. I do not see the road ahead of me. I cannot know for certain where it will end. Nor do I really know myself, and the fact that I think that I am following your will does not mean that I am actually doing so. But I believe that the desire to please you does in fact please you. And I hope I have that desire in all that I am doing. I hope that I will never do anything apart from that desire. And I know that if I do this you will lead me by the right road though I may know nothing about it. Therefore will I trust you always though I may seem to be lost and in the shadow of death. I will not fear, for you are ever with me, and you will never leave me to face my perils alone.
Creo en Dios! 
I am saving that one…
