In this zoom Bible study Mr. Smith continues looking at some of the key words used by John in his gospel. In this study he looks at the words "light" and "witness." John tells us that Jesus is the light of the world because of the truth of God that he reveals to us. In his use of the word "witness" John shows eight ways that the truth of Jesus teachings are established. Among these are Jesus' miracles, his fulfillment of prophecy after prophecy during his life, and by the witness given by some of Jesus' apostles in the written words of the New Testament.
