These laws give water the properties which we observe. Without these laws water could not serve the purpose for which God created it. We too, are given laws. In disobedience to these laws we experience death. In the obedience of these laws we experience life.
Water makes up a huge portion of the creation.
It is a major component in man. It is a major component of the earth. Much of the atmosphere is water vapor. God created water with the properties which we observe so that our life could exist. In God's providence he continues to uphold and govern the creation.
