"e;The best theory for fighting fires comes from actually engaging in the battle against the flames,"e; Ray Anderson writes. "e;For the thousands of pastors and church leaders who are on the 'firelines' of God's mission in the world, we need a theology that sings, even as it stings, igniting the mind and stirring the heart."e;In these pages, then, Anderson passionately sets forth a vision of the church's work and mission based on its birthday: Pentecost. At Pentecost, Christians were given the Holy Spirit in order to understand the incarnation and come alive to God. So this key event directs and empowers the church in its service to the world. In the light of Pentecost we learn that we can come to know God only in praxis -- truth discovered through action. In the process of elucidating this praxis, Anderson seeks to construct a theology that not only truly respects and aids ministers on the firelines, but will also heal the breach between Pentecostal and mainline church theology.
