"I Know" lyrics

I know what it means
to be lost in the dark.
I know what it means
to be tossed in the storm.

I have walked alone
with a heart of stone
and despair too heavy for tears,
but you caught my heart
and you taught my heart
to forget the doubts and fears.

And now that I know
the joy of your love,
my head is high, I can face the sky
and know that the heaven is here below,
I know.
For you I could die,
for you I will live,
I know.
