Preaching at open air mass gatherings exists based on the compelling belief that the Gospel was always meant to move beyond the walls of the church and permeate the areas where everyday life unfolds. With the example of Jesus and the early church driving this form of ministry, the message of Jesus reaches people of all backgrounds. This includes those that would never feel comfortable with entering a church building due to past hurt, fear, unfamiliarity or any other barrier. Moreover, it is an innate response to the command of Jesus to go into the world and preach the gospel. This act of obedience and urgency cultivates unity amongst people of all ages and backgrounds as they witness the saving, healing, delivering reality of Jesus and enables them to experience this hope together. This bold yet loving form of witnessing has historically proven to spark revival and lasting transformation in cities and nations around the world.
