The book of Acts tells the story of how God turned the world upside down through the earliest Christians and churches as they proclaimed God’s Word in the power of the Spirit. These followers of Jesus not only served one another—they served the world. In this message from the book of Acts, David Platt reminds us that, with the gospel as our foundation and motivation, followers of Christ today should live to make disciples and multiply churches to the glory of God. Just as it was for the early disciples, the cost will be great. But the reward is more than worth it.
