There is something puzzling in the Gospel accounts. Jesus heals people, drives out demons, and feeds multitudes. Yet people approach him and ask for a sign. What, exactly, do they think has been happening?
The familiar explanation is that they refuse to believe despite the evidence. That explains their persistence, but it leaves another question open: what kind of evidence would they consider worthy of God? Why can a person’s suffering be relieved before their eyes without that relief becoming, for them, a recognizable expression of divine goodness?
