The Gospel of John is the last of the four Gospels. This one is quite different from the other three. It starts not with a factual account of some part of Jesus' life, but at the beginning of time, using symbolic language to represent who Jesus is. There are no parables in this book but there's plenty of imagery, as well as seven of Jesus' miracles and seven 'I am' statements describing who he is. John shows Jesus as both fully God and fully man - God in human form.
The book of John shows the incredible nature of Jesus as fully God, but also as God in human form. Jesus experienced human life and knows what it is like to feel emotions, to struggle, and to experience loss, excitment and joy. He is a God who understands everything we go through.
