Let Go lyrics

Yeah I trust in You
I remember times You led me
This time it's bigger now
And I'm afraid You'll let me down

But how can I be certain?
Will You prove Yourself again?
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/barlow_girl/let_go.html ]
[Chorus:]
'Cause I'm about to let go
And live what I believe
I can't do a thing now
But trust that You'll catch me
When I let go
When I let go

What is this doubt in me
Convincing me to fear the unknown
When all along You've shown
Your plans are better than my own

And I know I won't make it
If I do this all alone
