It’s so easy for churches to become self-focused. Our own comforts and concerns slowly begin to swallow up our time, energy, and resources. But Christ’s command to make disciples of all nations should compel us to move out with the gospel to a world in need. This is the church’s mission. In this third sermon in a three-part series on Matthew 28:16–30, David Platt encourages the church to make disciples and to multiply churches, both in our own neighborhoods and among unreached peoples across the globe.
