How Do You Know

I've got my doubts and I've got my questions 
It's nothing new 'cause I've seen them before 
I've had my share of false revelations 
It always seems they're knockin' on my door 

You said that I should see the light 
But sometimes faith is blind 

How do you know, how do you know 
What I'm suppose to be doing 
Why do you go, why do you go on 
Thinking you know my fate 
So many times I've lost my step 
But never lost my way 
How do you know, how do you know 
When I don't know myself 

You're thinking that you've got all the answers 
You've got my situation figured out 
But you're only seeing part of the picture 
There's so much more that you don't know about 

And here you come to speak your mind 
But I'll say one more time
