Today's Lectionary invited us to set alongside each other two images - the tall, beautiful, strong cedar tree (35-40m tall, evergreen, wood and oil much prized) and the small, ugly, not so strong mustard plant (1-1.5m tall, often seen almost as a weed).
In each image (Ezekiel and Mark) the tree becomes a safe refuge for birds (and other species).
Jesus seems to be saying, that the Kingdom is like a pernicious weed, that is almost impossible to get rid of, and that seeds in amongst other plants (in contravention of Leviticus 19:19) destroying purity.
So what are we to make of this?
The Kingdom of God is low-level, spread widely at grass roots level, transforms all it interacts with and, eventually will take over. Here, in this unlikely, untidy, organic, powerless muddle, is peace, reconiliation and hope to be found.
I wonder, if it's a valid reading, what we do with that?
