Water...

This is going to sound a little weird I know, but I was just wondering, do any of you happen to know what water symbolizes from a Biblical perspective? I looked it up on the internet and found some various results, but I am curious to know if any of you have any thoughts on it at all.
The reason? Because someone told me once that I am, "like water", so I have been wondering what exactly that is supposed to mean. One of my friends was "like fire", but I could understand that.
Well anyway, I would love to have some feedback, so please comment me and tell me what you think.
