"in the confines of time and eternity"

Time and mortality 

the debris of a spoken word
withered petals of a glorious beginning
when it was spoken

 "in the beginning"

eternity and immortality

 the sustenance of a word spoken

 continuous ripples of a glorious beginning
from the moment it was spoken

 "let there be"

constellations that He shepherds
He knows them all by name
A third of the illuminaries 

torn by the dragon's tail
Futility pride failed to curtail

Witnesses of the Word spoken

 "it was good"
now confined to this debris 

of withered petals of creation
wrapped in the confines of time and eternity
