Poets have a way of stating mysteries in such a fashion as to make them both memorable and a permanent part of human reflection. A. E. Housman queried:

How odd

Of God

To choose

The Jews.

To which it has been added:

But not so odd

As those who choose

The Jewish God

And spurn the Jews.

Housman has identified the mystery of divine election. The other has identified the mystery of iniquity.
