Elegy For My Father, Who is Not Dead

I liked this poem but it was a little confusing. I was trying to decide what the overall message was. The father is obviously ready for death. On the other hand, the son is obviously not. I was trying to decide if there was another meaning though. It almost seems like it could be talking about faith and religion. The father has faith that he will have some sort of after-life. However, the son does not share this belief. These differing beliefs could boil down to differing views on God and His existence.
