One life, one short moment in time to decide what's wrong, what's right,
Just like a vapour of smoke, we are here and then we are gone, we're gone,
One life to make the choice, right or wrong, for eternity.

I know you think you know,
Anything you can't see, you refuse to believe,
Do you know what you think you know'
Is it bothering you that it may just be true'
I know you think you know,
Anything you can't see, you refuse to believe,
Do you know what you think you know'
Did you happen to find there's a doubt in your mind'

One man came and gave all that he had to give; there is no greater love, (no greater love)
Just like a vapour of smoke, we're here then we're gone,
And I know, I know,
One life to make the choice, right or wrong, for eternity, oh.

I know you think you know,
Anything you can't see, you refuse to believe,
Do you know what you think you know'
Is it bothering you that it may just be true'
I know you think you know,
Anything you can't see, you refuse to believe,
Do you know what you think you know'
Did you happen to find there's a doubt in your mind'

I know.

Do you know what you think you know'
Is it bothering you that you know that you know that it's true'

I know you think you know,
Anything you can't see, you refuse to believe,
Do you know what you think you know'
I know, I know,
Anything you can't see, you refuse to believe, (Do you know' Do you know')
Do you know what you think you know'
I know, I know.
