"Footprints In The Sand"
You walked with me
Footprints in the sand
And helped me understand
Where I'm going
You walked with me
When I was all alone
With so much unknown
Along the way
Then I heard you say
I promise you
I'm always there
When your heart is filled with sorrow
and despair
I'll carry you
When you need a friend
You'll find my footprints in the sand
I see my life
Flash across the sky
So many times have I been so afraid
And just when I
I thought I'd lost my way
You gave me strength to carry on
That's when I heard you say
I promise you
I'm always there
When your heart is filled with sorrow
and despair
And I'll carry you
When you need a friend
You'll find my footprints in the sand
When I'm weary
Well I know you'll be there
And I can feel you
When you say
I promise you
Oh, I'm always there
When your heart is filled with
sadness and despair
I'll carry you
When you need a friend
You'll find my footprints in the sand
When your heart is full of sadness
and despair
I'll carry you
When you need a friend
You'll find my footprints in the sand
