What are the qualities of the star?

The qualities the speaker attributes to the star are
steadfastness (line 1), patience (line 4), sleeplessness (line 4), and attentiveness
(“gazing,” line 7). He assigns to the star the role of guard or watcher, thus suggesting
that the star is like a divine presence, neither slumbering nor sleeping because of
eternal guardianship over the children of God. The words “forever” and “ever,” combined
with the attribution of the star’s being “steadfast,” provide a backdrop of permanence
for the speaker’s love, which he wishes would remain forever firm and steady. Granted
the comparative permanence of the stars, the choice of the star as subject is quite
appropriate.
