People are walking like trees!

As a boy I can remember travelling to Northern California on an expedition to the Redwood Forests that Arlo Guthrie sang about. One tree had a cut through which cars could drive - and it was still alive and soaring to the heavens. The reading from Mark 8:22-33 causes me to wonder about the first healing of the blind man when people are seen walking around like trees. (Sounds like a Tolkien story, right?) Then the second healing gives the blind man the whole picture. I wonder, could his first healing offer an impressionist view of God's purpose for us? Are we to be growing, as a blessing for others - like the mustard seed that grows into a cedar tree?
