Trowel and a Sword [EPUB ebook] 
Prayer Practices for Those on the Frontlines of the Gospel

This book is for anyone on the frontlines of the gospel, whether it be at work redeeming neighborhoods, working with the most vulnerable, or leading prayer and evangelism efforts. Prayer must take on a declarative, bold, and authoritative tone. To show up on the frontlines of the gospel without this form of prayer is the equivalent of bringing the proverbial knife to a gunfight. An effective gospel worker needs a trowel of evangelism in one hand and a sword of prayer in the other. Such a person will not only find their way to the frontlines, but they will also have what it takes to stay on the frontlines.
