Book excerpt: World-renowned New Testament scholar offers a straightforward examination of what the Bible says about the Holy Spirit. Who exactly is the Holy Spirit? What does he do in our lives? How can we know him more deeply, and is it possible to tap into his power? Should we pray to the Holy Spirit? Is it possible to be aware of his promptings and speaking into our lives? Dr. Scot McKnight answers these questions and more in this comprehensive examination of what the Bible says about this divinely important, but often confusing member of the Trinity. This is the third work in a three-part series examining some of the more mysterious components of the Christian faith. Scot's The Heaven Promise examines the afterlife. The Hum of Angels elucidates the Bible's teaching on God's supernatural messengers and protectors. Now, Open to the Spirit examines the most mysterious member of the Trinity. Scot blogs at Patheos, a large multi-perspective blog format. It serves many influential voices from many faith and non-faith traditions. Scot's blog draws primarily a Christian readership; one that is looking for intellectual engagement and thoughtful analysis of Scripture, Theology, and Culture.
