What is the concept of the first stanza of "Easter Wings"?
In this poem, Herbert is essentially praying -- he is directing this poem explicitly to God. It is a poem in celebration of the resurrection of Jesus Christ.
The first stanza of the poem is a discussion of why Jesus's death and resurrection were necessary and helpful to people. It mentions how God created man in a perfect state (as in the Biblical Garden of Eden) and then it goes on to that people lost that perfection. It says that people, through their own faults, became less and less perfect. (So wealth and poverty are metaphors for perfection and sin.)
