Mark and Patti Virkler take the unquantifiable and cut it into bite-sizes that make sense and which you can chew on. Hearing God's voice is taken out of the abstract "hit or miss" realm into something that you can be confident of and do everyday. I recommend this book AND Mr. Virkler's life seminars to all those who are wondering or frustrated what it really means to be able to hear God's voice as a precursor to personal obedience. This book is great, but I also recommend purchasing the live teaching CD or DVD as it makes it come alive even more. My life has totally be revolutionized by the four keys of how to hear God's voice.
