This booklet is so helpful! I have recommended it to my church elders, and friends. Now I wish there was a book which went into more detail, explaining the bits that the author has been too brief with, aimed at the people, like me, with no theological training. I have written out some of the points made and I refer to them when I am listening to sermons and taking notes. Preachers definitely need to read this, and learn from it too.
