What does the song ocean from hill song mean?

You call me out upon the waters
The great unknown where feet may fail
And there I find You in the mystery
In oceans deep
My faith will standAnd I will call upon Your name
And keep my eyes above the waves
When oceans rise
My soul will rest in Your embrace
For I am Yours and You are mineYour grace abounds in deepest waters
Your sovereign hand
Will be my guide
Where feet may fail and fear surrounds me
You've never failed and You won't start nowSo I will call upon Your name
And keep my eyes above the waves
When oceans rise
My soul will rest in Your embrace
For I am Yours and You are mineSpirit lead me where my trust is without borders
Let me walk upon the waters
Wherever You would call me
Take me deeper than my feet could ever wander
And my faith will be made stronger
In the presence of my Savior...

The main idea of the song is about stepping out in faith and trusting and really depending on God more  than what you usually do.
