A GOD-centric UPDATE that guides you to the Throne Room.
I was given the ORIGINAL version of this book as a gift—long before I knew about the prophetic as a realm ALL Believers can enter. I had several false starts reading the book. With each round of attempting to read it I stopped short for the same reason—I felt there was more emphasis on experiences and the author’s revelations than on the Word of God.
Fast forward to several years later, I decided to read this book again BUT by this time I had my own personal revelations and substantial teaching about the prophetic. I was/am still a WORD girl so as I prepared to read it I discovered THIS EXPANDED EDITION and boy was it a wayyyyyyy different read. EVERY IOTA of teaching is anchored in the word of God and turns it all back to the Godhead. There are endless stories of his or other giants’ personal experiences but EVERY account is in the framework of the Word of God. The Godhead is exalted in this book. EVERYTHING else is secondary. I absolutely loved this new writing voice—such that I have since bought another book by the author and I plan to read more of his works.
At the end of the day, heavenly encounters are purposed by God to draw us and others into deeper relationship with Him. The encounters and revelations are not the endpoint, HE is—His Word, His will, and His way. This is the thesis statement of this book and I love it!!!!!!!!!!!!

Seeing in the Spirit is biblically valid - book helped me understand & lose my fear/confusion about the supernatural
Wow! I read this book over the course of just 2 days. I bought it a while back but hadn't read it until now. I had some fear with seeing in the spirit realm. After reading this book, I have a MUCH greater understanding. I am also now interested in contemplative prayer - which James Goll briefly touches on in this book. I am willing to finally leave prejudices behind about the wonderful and supernatural means that God DOES in fact use to communicate with us. I have bought into the lies that this is somehow of the occult or non-biblical. Further inspection of the scriptures for myself (away from any teachers - no matter how great I thought they were) showed me this is not the case. God DOES speak to us, He DOES manifest Himself to us when we obey and love Him, and there IS a tangible, actual presence of God. What a shame this is being demonized in many Christian circles because there is NOTHING more wonderful and joyous than God's actual presence. Seeing in the Spirit is also another way God interacts with us. I have abandoned my fears and have come to realize how truly amazing this really is.
The Bible is filled with visions, dreams, divine interactions, etc. Any person reading the Bible - setting aside other opinions influencing him/her - will plainly see that the gifts will not cease until the return of Jesus Christ. Also, that we are to hear God's voice and commune with Him. John 5:39 - hit me hard during a terrible time of fear and confusion because of all the various doctrines on this topic. "Search the scriptures: for in them ye think ye have eternal life: and they are that which testify of Me. And ye will not come to Me, that ye might have life." We don't know Jesus through the Scripture, we know about Him from the Scripture. We do have to go to Him and seek Him in addition to studying the scriptures. He is a real Person, and this is a real relationship.
I tabbed the section James Goll wrote on testing the source and testing the spirits as this is something that I have not always done and now have excellent information about from this book. I also have reassurance that this does not offend God and/or Holy angels - as this is what we are told to do. I highly recommend this book - and I think it would be tremendously awesome for more Christians to leave the fear of deception, fear of the devil, and fear of the religious folks ridicule behind. We are able to enjoy a *REAL* relationship with Christ even during our time on earth.
