I have noticed that many editions of Vos' Grace and Glory sermons contain about 6 sermons. However I noticed that the 1994 Banner of Truth edition (now out of print) is about double the size and appears to be an expanded edition. Did the Banner edition add extra sermons? Is it worth looking for a expanded edition? If so, does anyone know where one can get this for a reasonable price. Amazon and Abe Books sell second hand copies but their listings sell them for well over US $100! I live in New Zealand so sensitive to extra exchange rate and postal costs. Thanks.
