I chose "I am the Light of the World" because when i look around at the condition of the world (people), i see people trying to find their own way through life using their own self-made road maps. They have their own versions of right and wrong, their own truths and they all want to be masters of their own fates, captains of their own ships. People are walking around in a fog, in a daze trying to figure out what life is all about. Some want to live without rules to govern them, without God telling them how to live; others want God in their lives but on their terms, and so they are stumbling in the the darkness, in the chaos of this world. All a true believer has to do is look around via the television, radio or internet we can see confused men and women and even conversing with them will tell you they are confused, in a state of darkness. When Jesus declared I am the Light of the world” (John 8:12) which is the second of seven “I AM” declarations of Jesus, recorded in John’s gospel, it characterizes His unique divine identity and purpose. In declaring Himself to be the Light of the world, Jesus was claiming that He is the exclusive source of spiritual light. No other source of spiritual truth is available to mankind.
According to my commentary studies many in the old testament draw attention to the ceremonies with lights at the Feast of Tabernacles and suggest that Jesus was consciously fulfilling the symbolism suggested by them (John 8:12-30).
Bible studies teacher and contributor Robert L. (Bob)Deffinbaugh added there is nothing unlikely in this, especially if the words were uttered reasonably close to the time of the Feast. The feasts were very important to the Jews. They delighted in their observance and rejoiced in their symbolism. And it was important to the Christians that the Christ fulfilled all the spiritual truths to which the feasts pointed.
