A church too may die or become a remnant

A church too may die or become a remnant.
Pews may empty. And even dutiful hearts
grow dubious, with good intentions spent.
Faith comes with daylight and in darkness departs.
A church too may die or become a remnant.

Gold, silver, bronze, iron: each age alloys
its predecessor.  Know spirit is a seal
we may not break.  Shut out the world's noise.
Keep this circle safe where we share our zeal.                 
A church too may die or become a remnant.
