As soon as Peter and John were set free, they returned to their group...(Then)... the believers... all joined together in prayer to God: Master and Creator of heaven, earth, and sea, and all that is in them ... allow us, your servants, to speak your message with all boldness... When they finished praying, the place where they were meeting was shaken. They were all filled with the Holy Spirit and began to proclaim God’s message with boldness. (Acts 4: 23-31)
