After Jesus ascended into heaven, His followers were tasked with spreading the good news of salvation "in Jerusalem, and in all Judea and Samaria, and to the end of the earth" (Acts 1:8). The book of Acts details the early church's rapid growth as they received the Holy Spirit and carried out the Great Commission to a world that was hungry for it. In this verse-by-verse study, Skip Heitzig teaches how we can be effective witnesses for Jesus Christ in the world today, and we learn how God continues His work through the Spirit-empowered church.
