Here is what Brad wrote…
Concerning Prophetic books, I would recommend several:
1. Understanding Prophetic People: Blessings and Problems with the Prophetic Gift by R. Loren Sandford - This book is a sound look at the character development that prophetic people will go through. This is one of the most well rounded books that would be good for someone who wants to understand the gift of prophet. Sandford does a great job of exposing the excesses.
2. How to Hear God’s Voice by Mark Virkler - Prophetic or not, every believer should read this workbook. This book is a classic that has helped many of today’s top prophetic people get their start. It is a sound, practical approach to hearing the voice of God.
3. The Seer: The Prophetic Power of Visions, Dreams, and Open Heavens by James Goll - For those who have open visions or are Seers, this is a good book that will help them understand their gifting.
The only other books that come to mind would be Graham Cooke’s new titles. I have only read bits and pieces of them, but he is a sound prophetic voice. End of Brad's recommendations
Personally I have only read Jim Goll's The Seer in its entirety, which I thoroughly enjoyed and found useful. Jim applies an exhaustive biblical study on this seer dimension that I am comfortable with—whereas, some other prophetic voices out there tend to gravitate towards “techniques” that are questionable. All prophetic activity stems from an intimate relationship with the Godhead—namely, the Father, the Son, and the Holy Spirit. Techniques can never substitute for an authentic pursuit of the hidden life that is found in the secret place in Christ. On the basis of His ongoing pursuit of us, we must pursue the deep things of His heart through the crux of the Cross. May your heart be stirred right now even as you read this to pursue the One who has pursued you! May your inner man desperately long for greater revelation of His great worth, His great splendor!
