On Sponges...

I read a quote that has me turned on my head. Saint Teresa of Avili said:

"It seemed to me there came the thought of how a sponge absorbs and is saturated with water; so, I thought, was my soul, which was overflowing with that divinity and in a certain way rejoicing within itself and possessing the three Persons. I also heard the words: “Don’t try to hold ME within yourself, but try to hold yourself within Me.”

This has me thinking...am I a sponge? Do I want to be a sponge...sometimes dry and empty, sometimes damp, sometimes overflowing and saturated? Or...do I want to be the water, soaking into the sponge that is God, soaked up and absorbed into Him?
