Answer:
The sentences portray the contrasts of the events taking place by creating imagery.
Step-by-step explanation:
With the heavenly scene, the darkness of the night sky and perhaps any stars that may be there contrast with the ocean line in the distance, separating the two. The heavenly scene may have some sort of biblical reference or meaning, or it may just be describing the view as something beyond wonderful, something blessed or holy.
The visible horizon contrasts against the night sky. The best way I can describe this is the way the darkness of the houses blocks out the light of possible stars in the night in the distance.
The edge of the horizon once again refers to the contrast between the ocean line and the sky.
