A Song For Those Longing For a Lasting City

Some of my favorite lines in this song:

Mine are days here as a stranger 
Pilgrim on a narrow way 
One with Christ I will encounter 
Harm and hatred for his name 

But mine is armour for this battle 
Strong enough to last the war 
And he has said he will deliver 
Safely to the golden shore 

And mine are keys to Zion city 
Where beside the King I walk 
For there my heart has found its treasure 
Christ is mine forevermore
