Good Morning, Holy Spirit is a best-selling book by Benny Hinn on the person of the Holy Spirit. Hinn teaches that the Holy Spirit should be understood as a concrete person of the Trinity rather than an ethereal, abstract figure, and claims that this is taught in both traditional Judaism and Christianity. Despite the success, the book was criticized for not conforming completely to Christian teachings. The book was first published in 1990, then revised and expanded in 2004. Millions of copies have been sold.
