Analysis of Children of the Promise

Children of the promise rarely live an easy life.
Instead its marked by suffering and has its fill of strife.
One day is very pleasant as your promise fills the room.
But other days are awful and they’re only filled with gloom.
The light breaks through the darkness; and the darkness is destroyed!
But in this life, there’s trouble that a man cannot avoid.
I hear the birdies singing in a grove of barren trees.
The sound of all their voices is just so hard to believe.
The sing although they have no food; their little bellies empty.
We sing because we trust in God! Let not this world temp me.
