This is something I've been pondering for a while, and I admit up front that it is something that is NOT fully developed. But I wanted to at least begin getting my thoughts about it "out there."
So, with that disclaimer out of the way, here goes.
It's no secret that liquid is absolutely essential to life on Earth. Water, blood, milk, and even sweat and saliva are all forms of liquids required for daily living. Without even one of these, life as we know it would be radically different.
Liquids even take on more extreme and wondrous forms, in different sweeteners (honey, maple syrup), poisons (rattlesnake venom, harvest mite saliva), oils (olive, coconut), acids (hydrochloric, vinegar), body fluids (rennet, cerebralspino fluid), and so on, each one taking on a more incredible and specific form than the last.
We also know that
"The heavens shew forth the glory of God, and the firmament declareth the work of his hands." -Psalm 19:1
So what do fluids reveal about God?
