What does this mean?

I’ve gotten some weird emails, but one of the weirdest ever just arrived:

Dearest Nat(h)an,

Since I have always been a service to others, verily, verily I say unto thee:

What shall it profit a man if he gains the whole world but loses his soul?

Very truly, I tell you, servants are not greater than their master, nor are messengers greater than the one who sent them. If you know these things, you are blessed if you do them.

Yes I am with you always, until the very end of time.

You may turn your back. You may choose to ignore me with scorn in your gleaming eyes.

But I shall remain, for my middle initial is Z. If Z is taken away, then the bookholders
that consist of the letters A and Z will only have A, and people’s books will not be able to stand.

A culture of ignorance is not what I wish to promote. If I had have read further instructions on how to
carry a cross better, maybe I wouldn’t have almost been kicked out of the parade. Or maybe I should
have been kicked out and then I wouldn’t have died. SHIT!

Jesus Z. Christ
- Because I am the FINAL letter of the law.
