Nathanael said to him, "Can any good thing come out of Nazareth?" Philip said to him, "Come and see."

 So John is saying: "Into this world there comes Jesus, the light of the world; there is a darkness which would seek to eliminate him, to banish him from life, to extinguish him. But there is a power in Jesus that is undefeatable. The darkness can hate him, but it can never get rid of him." As has been truly said: "Not all the darkness in the world can extinguish the littlest flame." The unconquerable light will in the end defeat the hostile dark. John is saying: "Choose your side in the eternal conflict and choose aright."
