There is a great talk by Dr. Russ Moore on "What About the Man on the Island?" found near the bottom of this page: http://www.sbts.edu/resources/audio/Collegiate.php. There is also an excellent book by Dr. Ron Nash called "Is Jesus the Only Savior?" He gives a talk based on the book, and it can be found on that page as well.

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
