To those who want to look further into this question, but want a non-Catholic-Christian source, may I suggest reading The Gospel of the Kingdom by Philip Mauro.
I'm not criticizing the article that was posted at all (I agree with it), but I recognize that some people who are not Catholic may prefer additional, non-Catholic, sources.
Dispensationalism, and the Scofield Reference Bible, are a modern invention and are heresy to any Christian.
That book, The Gospel of the Kingdom by Philip Mauro is very good.
