《When You Know》的歌詞如下：
When you know
When you know you've been set free
When you know that there's no turning back
You'll feel the trust you've been dreaming of
You'll find a way to speak your heart
And the pain of holding back will end
You'll let yourself be loved again
And when you know
You'll run to face the danger
When you know that there's nowhere to hide
And it's right and it's wrong and it's all that you've ever known
You'll take the chance that you've been given now
And when you know you've got to let it go
When you know that there's nowhere to run
And it's now or never, here and now
You'll find the courage to let it happen now
You'll feel the trust you've been dreaming of
And when you know, when you know...
