Continuing our I AM series, we go back to what is at the heart of the Christian faith, and examine Jesus, and his revelation of God. There are seven times in the Gospel of John where Jesus said 'I am', and gave a series of images that explained who he was. This week, we look at Jesus when he spoke of himself as 'the light of the world' in John 8:12-20. Sam Oldland gives us his first talk at St John's, and looks at what this means, with Jesus as the one who sheds light on the darkness, and saves us from it.
