Jim Cymbala emphasizes the call for all Christians to be bold witnesses for Jesus, highlighting the urgency of sharing the gospel with the world, which is filled with people who do not know Him. He reminds the congregation that the last command of Jesus was to go and preach the good news to all creation, and that every believer is empowered by the Holy Spirit to share their faith. Cymbala stresses that witnessing is not just the job of clergy but of every disciple, encouraging believers to speak boldly about their faith despite the hostile environment. He concludes with a prayer for boldness and the assurance that God will back them up as they share the message of salvation.
