《Be My Heart》的歌詞如下：
女：
Let me be your light
Through the darkest nights
Cause I’m on your side
Through every storm
Through every test
I’ll be your strength
When you’re feeling weak
男：
Just let me be your love
Your guiding star
To illuminate
Your every step
Through every valley
To the mountaintop
I’ll be your strength
When you feel weak inside
女：
Be my heart
When there’s no more hope left
Be my heart
When you’ve given up the fight
Be my heart
Cause you’re all I need
To keep me strong and alive
男：
Through every tear
I’ll be your shield
I’ll make all the pain worthwhile
Through every pain
You’ll find a way
I’ll be your strength
When you feel weak inside
女：
Be my heart
When there’s no more hope left
Be my heart
When you’ve given up the fight
Be my heart
Cause you’re all I need
To keep me strong and alive
And we will rise up higher than the clouds, higher than the sky.
We will rise up, we will rise up, we will rise up.
Cause I am here for you, you are here for me.
Together we will rise up.
Be my heart.
Be my love.
Be my everything.
Cause you are all I need.
To keep me strong and alive.
To keep me safe and sound.
Be my heart.
Cause you are all I need.
Be my everything.
To keep me strong and alive.
Alive.
Alive.
Alive.
Alive.
Alive.
