In the book "Developing Aposotlic Strategy" I share this powerful spiritual warfare strategy in "The Principle of Mass." This is one of the key principles that has empowered so many churches to begin to transform their communities documented in "Operation Rolling Thunder - Revised." There is truly exponential power generated when we agree. One can put a thousand to flight and two ten thousand. I want to encourage you to be like Abraham who trained his household to war for their family members (Genesis 14). This is critical to your family's destiny in Christ and you can play a very important role in building the wall of prayer in your church which can also help transform your city.
Matthew 18:19“ - Again I say to you that if two of you agree on earth concerning anything that they ask, it will be done for them by My Father in heaven."
