God is at work in our lives, invisibly at work, like a seed growing in the darkness, like yeast rising in a loaf. The work of faith is to identify and make sense of the thin places. That means never losing heart. It means to keep taking, and planting, and mixing in faith. It is no accident that small acts affect lives far beyond our view, our power, our lifetime. That's true because God is faithful. God is at work in the invisible world that rubs up against, and breaks through, into this visible one, while remaining invisible to us.
