A lot of it is in reaction to the extremes of the classic Scofield/Chafer type of dispensationalism, which WAS dispensationalism in the 30s or 40s when he wrote those articles. I'm not saying it isn't worthwhile to read it today, but a lot of the stuff that he focuses on (at least to my recollection) isn't going to really register with most dispensationalists today. Many will say "That's not what I believe!" I'm referring to the teaching that many OT passages as well as some in the gospels cannot be applied to the church age believer at all, and that certain promises that were made to Israel cannot be appropriated by the believer. At least some copies of this work are entitled "Application of the Scriptures: A Study of Dispensationalism" which, I think suggests what his issue was.
You can read it on Monergism or Chapel Library. I think I have an old copy from Chapel Library somewhere. Monergism notes that it is dated. I think it is even a little more dated than they suggest. Pink read a lot of Plymouth Brethren writers in his early years, and some of his early expositions like Genesis and Exodus are influenced by that. Someone who has read a lot of Ryrie or Walvoord is going to have some differences with Darby, Scofield, etc in that they are not as extreme in asserting that some things cannot be applied at all in this age.
I think Grover Gunn or Vern Poythress or something else more recent would be better if you are looking at something that delves into the rapture, premil, Israel, etc. As with most of Pink's works, it originated as a series of magazine articles and doesn't cite sources the way that a more scholarly book will.
I'm assuming you haven't read it yet. But perhaps you have and you want to discuss something in it?
