As a result of the growing worldwide prayer movement, powerful changes have taken place in the church and in scattered cities' transformations beyond anything imaginable only a few years ago. Of the revelations to come out of this movement, perhaps the most dramatic and promising is the rediscovery of biblical principles for changing the spiritual climate over entire cities and regions. Fulfillment of the Great Commission is no longer a distant hope but rather a fast-approaching reality for a worldwide church that will take hold of and use the biblical principles for changing cities as described in Prayer Evangelism. Silvoso shares his heart and his passion for reaching cities the way the early church did it: the whole church modeling the whole gospel to the whole city through prayer and prayerful evangelism.
