You stand like a rock
or a tall oak tree
just behind me
To catch me if I fall
or need someone to lean on
when the darkness calls

You have been my help
in times of need
A wonderful feeling
it will always be
When darkness calls
you stand by me

Your roots run deep
and on your strength I rely
You quiet me so I can sleep
Harbored within these walls
the need of someone
when the darkness calls
