Ever since the church was founded, Satan has attempted to oppose God’s people. However, the book of Acts teaches us how God worked in and through Christ’s early disciples for the spread of the gospel, even amid persecution and opposition. In this message based on Acts 4–8, David Platt points us to the early church as an example of a people who—though imperfect—relied on the power of God to carry out the church’s mission. We too can have confidence in God’s power as we seek to live faithfully in our day. Christ has given us his Spirit, and he has promised to build his church. Our mission is therefore unstoppable.
