The world is full of mysteries. Many are intrigued by earth's mysteries UFO's, the lost city of Atlantis, the pyramids, the Nebula of Orion, etc. God knows the answer to every mystery. However, as interesting and captivating as these mysteries are, they pale in comparison to the revelation of the deep secrets of God. The Holy Spirit may seem a mystery to some people, but God's desire is for His believers to know and understand the deep things of the Spirit. "God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God" (1 Corinthians 2:10). Because of ignorance, fear, and tradition, many have chosen to ignore teachings concerning the Holy Spirit. In this book, Dr. Larry Ollison sets aside religious political-correctness and digs deep into the mysteries of the Holy Spirit. Remember the final words of Jesus as He ascended into heaven from earth: "You shall receive power when the Holy Spirit has come upon you" (Acts 1:8).
