Joshua Harris has written several other books, which I have not read personally but I did enjoy this small, well written book. The basis of the book is that we must not puff ourselves up as Christians so that we can make others feel less worthy, less loved and less valuable to God. The book is short and an easy read in a few short sittings. The book discusses that we cannot be arrogant or boastful in our successes because often that is exactly what keeps the “unorthodox” from achieving the same freedom we have in Christ. Well worth buying even if the book is less than 70 pages long.
