Just a word of advice: don't let the title mislead you. This is NOT a book of classroom-oriented Sunday school lessons. The term "bible study" here has a very different meaning. Think of it instead as a mini (really mini) Systematic Theology. :-)The book's 25 chapters each cover a point of doctrine (such as "God and Man", "Christ the mediator", etc.) and consist of a page or two (sometimes a few) which list several bible passage references supporting that doctrinal theme. Each passage reference (book, chapter and verse number, not any specific translation's text) is also followed by a sentence or paragraph of commentary from Schaeffer. So the collection of passages serve as a quick guide to understanding the biblical warrant for the chapter's title topic. This is what is meant by "bible studies".I'm not knocking it, but it's just not what I expected at all, even with the book description. I accept the blame for not realizing "bible study" could have this other meaning. I just wanted to help other readers who may expect it would be a book of "classroom lessons". Even so, it can surely be a blessing to readers. Fortunately, Christianbook offers here links to the book's table of contents and an excerpt. I missed looking at those before purchasing. Be sure to check it out to be clear on what the book offers.
