Unstoppable

It comes in all forms
Slow, steady, fast or raging
It never stops, constantly moving
Always running, never walking

It's like glass
To touch is soft and cool
But it can also be rough and painful
It can burn or freeze

Man alone can not control it
It is strength and peace
You see God's power in it
It brings destruction and new life

A mixture of all things
There are many forms 
Rivers, creeks, oceans 
The mighty element water

This one isn't great, but not horrible either
