What are the meaning of the sentences in the poem The Man with Hoe?

The Man with the Hoe, by Edwin Markham is a poem written about a painting by Jean-Francois Millet: "L'Homme a la houe," which is "the man with the hoe" in French.

The second and third stanzas are comparing what a hard working man is to the ideal of man's creation. The second stanza starts with "Is this the thing the Lord God made..." and the third stanza ends with "Cries protest to the Powers that made the world, / A protest that is also prophecy." ... The poem seems to be saying that humanity isn't living up to what God wanted, or what he promised, and that he could have and should have done better, or prevented the world from allowing man to get to this state. In these stanzas and throughout the rest of the poem I think there is a lot of responsibility placed on humanity as well... that we will be judged for what we allow to happen to each other.
