Hebrews 13:8. There is nothing more powerful than a personal testimony. Acts 6:10, 15. Steven became the first martyr as he testified about the power of God. People are not interested in what we have to say, they are interested in what He, Jesus Christ, the Word of God has to say. Colossians 1:27. When they looked at Stephen they they thought that they were looking at an angel, because they could see Christ in him. When Jesus speaks, we need to listen up.
