A robust theology of the Holy Spirit can help build strong local churches and transform local communities. Drawing on ancient and contemporary church movement, including Holy Trinity Brompton and the Alpha course, this book suggests an understanding of the Spirit as the one who draws humankind and the whole of creation into the love that exists between the Father and the Son. From that starting point, it works out the implications of this for the Christian experience, the church's evangelism, its communal life and its transformational role in local communities.
