You are wondering what all this means. You are wondering what I am trying to say. I cannot tell you.
Somewhere out of sight, the sun pierces the cloud-muffled atmosphere for a moment, and suddenly the leaves are green, and bright. We think of color as something intrinsic (disregard the oddity of the chameleon's skin), but really everything depends on the light.
I cannot tell you because I do not know what I am trying to say.
But I'm certain that if we look deep enough, we will discover that it has something to do with God. He is the heart of everything. He is the wind that stirs us, the trunk that roots us, the sun that colors us, the window that shows us the world outside our own.
I know we have heard these metaphors before. We have heard them all our lives. And yet, we still don't understand.
