This devotional book of 40 essays, with each marked by two word titles, aims to give new entry points for understanding the Christian season of Pentecost. The outpouring of the Holy Spirit upon the disciples and followers of Jesus literally changed the world. These humble folks were eventually described by onlookers and critics as ones \"who had turned the world upside down.\" How did that happen, and what were the circumstances surrounding their life-change? These essays lead the reader to reflective meditation, and open the door to an encounter with God the Holy Spirit.
