Water is the most abundant liquid on the planet, covering approximately 70% of the earth's surface. Coincidentally or not, we are mostly water - human bodies are 50 to 75% water. Pure water is tasteless, odorless and colorless, although it does have a blue tinge in large volumes. The familiar chemical symbol H2O means that water molecules are composed of 2 hydrogen atoms and 1 oxygen atom.A Symbol Of Purification
"but whoever drinks of the water that I shall give him will never thirst; the water that I shall give him will become in him a spring of water welling up to Eternal life" (John 4:14 RSV)
