Did Jesus really call a desperate Canaanite woman a dog? Did he really tell her that he only was sent to Israelites? Was Jesus xenophobic? Was he testing her faith? No! There's a a much more encouraging way to understand this Gospel story.
What was Jesus getting at when he told his disciples that if they only had faith like a mustard seed they could cast trees and mountains into the sea? Russ Hewett proposes that Jesus wasn't giving instructions for working miracles here, but the tree and the mountain represented what was wrong with how they had understood God.
