The caterpillar-into-butterfly thing has been used to death as metaphor, analogy, inspirational image... I myself often bring it up when talking to sponsees about the idea of "Divine discontent."
It's also a wonderful (and common) way to talk about Faith; about the idea that God (if there is one, and today I'm voting yes) has something better in store, something bigger, if we but trust the process.
Usually when I think about it I somehow imagine the caterpillar not really knowing what's involved, but just taking each step as it comes.
But what if it did know? Who could blame Mr. C for doubting?
Caterpillar: "Let me get this straight. You want me to go into a small, dark space and remain totally motionless, and that is going to open up a whole new world for me."
God: "That's right."
Caterpillar: "So... I'm going to gain wings by... lying still."
Caterpillar: "I get the sky... by lying in the dark."
Caterpillar: "Riiiiight. Sure I will."
It struck me, as I thought about it this way, that a Divine process -- wherever one is or whatever one might be going through -- may look, from our perspective, like one is moving in the completely opposite direction from where you will ultimately be.
That makes faith a little easier for me today.
