The Harbour and The Cross lyrics

In the dead of the night While the city sleeps sound There's a weight on my shoulders Pulling me to the ground But who is my anchor When the dark tide pulls in? Who wears this iron armour So I can breathe in my skin? And I cannot yield And I cannot fail This burden of strength Leaves me gasping and frail And I cannot yield And I cannot fail This burden of strength Leaves me gasping and frail 'Cause I am the pillar The stone that won't fall The unseen defiance, the unheard call Perhaps it's the toll for a life given away And I cannot yield And I cannot fail This burden of strength Leaves me gasping and frail And I cannot yield And I cannot fail This burden of strength Leaves me gasping and frail 'Cause I am the pillar The harbour and the cross Who saves the saviour when the walls cave in? When the walls cave in?
