Revelation 1:3a

Simply reading the book of Revelation, puts a blessing on you, the reader. Doing what it says puts another blessing on you, the doer.  

If you read this thing and do what it says, you get 2 blessings.

That God would put such a free and easy to attain blessing out into the world gives me hope.

There are people who read the book, didn't get it, or didn't believe it, it just wasn't their thing.  They still get 1 blessing.  That's a great deal!

I've said, "read", however, the word is, "hears".  So, you didn't mean to hear the street preacher, wrong place wrong time, you still heard it.  That's still one blessing.
