Welcome back to another episode of the unSeminary podcast. Today we’re talking with Zenzo Matoga, Senior Pastor of Impact Church in Boston, Massachusetts. Originally from Malawi, Africa, Zenzo brings a passion for evangelism shaped by the revival crusades of Reinhard Bonnke. Under Zenzo’s leadership, Impact Church has become one of the fastest-growing churches in America, thriving in one of the nation’s most unchurched cities.



Is your church struggling to move evangelism from a program to a culture? Zenzo shares practical strategies and spiritual insights that have helped Impact Church ignite revival in a spiritually dry place, equipping believers to impact one person at a time.




* Finding your city’s key. // Every city has a spiritual “key” that unlocks its people, and every church has a unique calling. For Boston, Zenzo identified young professionals as a primary audience. By fostering authenticity and sharing real-life stories, Impact created an atmosphere where unchurched people feel welcomed and understood. Zenzo stresses that pastors must seek God for the specific key to their city rather than copy other churches’ models.



* The power of authenticity. // Millennials and Gen Z are drawn to honesty and transparency. At Impact, leaders openly share personal stories—including struggles in marriage or faith—so that people see church as a place of grace, not perfection. This culture of authenticity empowers members to share their testimonies, creating an environment where evangelism feels natural and accessible.



* Impact One. // Zenzo’s book “Impact One: The Epic Prayer That Transforms Friends and Family” grew out of a desire to help every believer reach their unchurched loved ones. The book teaches a simple four-step process: First, gain a burden for the lost—pray for God to break your heart for what breaks His. Pray for one—write down three names of people far from God and pray for them. Practice friendship evangelism—become a genuine friend with no agenda. And finally, seal the deal—when the time is right, share your faith boldly. This framework equips everyday believers to live as “producers” of disciples rather than passive attenders.



* Embedding evangelism in the culture. // At Impact, evangelism isn’t a program—it’s woven into weekly practices. Every Sunday, the church prays the “Impact One prayer”: God, please give me one person to impact with your love and invite to church. Testimonies of changed lives are shared regularly, reinforcing a culture of outreach. Members are even encouraged to ask one another, “Who did you impact this week?”—keeping evangelism front and center.



* Practical systems for connection. // Impact Church uses two creative tools to make disciples. “F15” stands for the first 15 minutes after service, when members are encouraged to treat the lobby like a mission field, seeking out new people rather than gravitating toward friends. The “C.L.O.N.E.” model—Chronology, Location, Occupation, Number, Encouragement—gives members a practical framework for conversations that lead to authentic connections and ongoing discipleship.



* Radical worship as evangelism. // Zenzo bridges his background as a worship leader with his passion for evangelism. He believes radical, joy-filled worship breaks spiritual strongholds and attracts unbelievers seeking something beyond what the world offers. In a city defined by intellectualism and materialism, Impact’s passionate worship embodies the presence of God in a way that draws people to conviction and freedom.



* From evangelism to discipleship. // Impact emphasizes that inviting someone to church is only the beginning. Members are encouraged to disciple those they bring—offering rides,
