The Greatest Words Ever Spoken by Steven K. Scott is a reference book which contains all the words of Jesus organized by topic. Each major section contains introductory remarks from Scott. This is a helpful resource for Biblical study and devotional reading though it is not exhaustive. I have used it several times in sermon and teaching preparation and it will probably continue to be resource on the bookshelf in my office/study.
I do have two words of caution:
First, keep in mind that these kind of compilation works rip passages out of their original context. That’s not a problem, per se, unless this book is your only resource on a topic. Ultimately, each passages needs to be understood in the context given by the author of the Biblical book.
Second, keep in mind that this book isn’t exhaustive. I put the book to the test while doing some research on the Kingdom of God/Kingdom of Heaven. I noticed that it included the text from Matthew 16:16 – 17 (Peter’s confession of Christ) and Matthew 16:24 – 28 (If anyone comes after me he must take up his cross) but it excludes Matthew 16:18 – 19, which actually contains the words “I will give you the keys to the kingdom of heaven…” I’m not sure if this is an error on the part of the author or if the passage is excluded for some other purpose. Either way, I trust the book a bit less to provide me with everything Jesus said on a given topic.
In conclusion, it’s a worthwhile resource, but it shouldn’t be either the only or main resource when researching Jesus’ teaching on a given topic.
