Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.

This award winning documentary was brilliantly produced and directed. But more importantly, Greg's story is a true example of God's redeeming love, grace, healing and mercy. I worshiped at Greg's church years ago and have kept up with him over the years and marvel at the anointed power of his messages. When I heard this story for the first time I had no idea his life had been so difficult growing up. To see what the Lord did for this broken, lost little boy is a magnificent testimony to His colossal love for us. Greg has been tested on the anvil of adversity, and his story has profoundly affected my life and faith. As powerful as his ministry was before, it is even more so now. When I go through difficult times, sometimes his story comes to me and I say, "There is hope indeed. God will get me through this.This DVD is a powerful tool for evangelizing. Glory to God for His all consuming love that gives us such hope.
