When Jesus was about to return to heaven, He commissioned the disciples to be His personal representatives: “You shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me . . . to the end of the earth” (Acts 1:8). The disciples had spent three-and-a-half years listening to Christ’s words and observing His actions, including His death and resurrection. “This Jesus God has raised up, of which we are all witnesses” (Acts 2:32). When Christ’s followers gave their hearts unreservedly to Him at Pentecost, the risen Christ transformed their lives through the power of the Holy Spirit. They became witnesses not only to Christ’s bodily resurrection and ascension, but also to His resurrection power, which had changed their lives. As Christians, we are also witnesses to the resurrection of Jesus, because we have experienced His renewing power in our own lives. Request this study guide to find out more.
