Best-selling author Bill Johnson describes His decades-long intimate relationship with the Holy Spirit as "the adventure of a lifetime." You have the same opportunity for a life-defining "adventure" into God's presence, love, and power by coming to know His Spirit. Many people are unfamiliar with who the Holy Spirit is and what role He has in their lives. They may be confused about or even intimated by Him. Even many seasoned Christians have an easier time relating to God or Jesus, while the Spirit and His ways are often a mystery. Like Jesus's disciples, we wonder why Jesus had to leave earth so that the Spirit could come. In one sense, the Holy Spirit is surrounded by mystery because He is Spirit. But He is also personal and knowable. In fact, spiritually, we literally can't live without Him and the life He brings us. The Holy Spirit is Bill Johnson's foundational book on the Spirit, including both introductory and deep truths about the third person of the Trinity. He describes what he has learned about seeking God, hosting His presence, and seeing His Spirit change the atmosphere of families and communities--bringing peace where there was anxiety and discord, salvation where hope was gone, and restoration where purpose was lost. Johnson guides you into a close relationship with the Spirit--an eternal wellspring available for everyone, every day, everywhere, for every need and calling. Let the Spirit fill and overflow your life as He moves, shapes, cleanses, and carries you along in the adventure of God's purposes for the world.
