John 8:12 I am the Light of the world; he who follows me will not walk in the darkness but will have the Light of life.
This really is the substance of Christmas. Jesus came down to earth in the form of a human, to bring light into the darkness. People who were walking in darkness had the opportunity to see the great light. The image of light dispelling darkness is central to our understanding of the Gospel. Isaiah 9:2 says, ‘The people walking in darkness have seen a great light; on those living in the land of deep darkness a light has dawned. Jesus’ birth was acknowledged by the light of a star over the manger in Bethlehem. This moment marked the turning point in history from the age of darkness to the age of light.
When Jesus was presented at the temple after he was born by Mary and Joseph, the old man Simeon, who had been waiting for His arrival, saw Him and acknowledged: ‘a light of revelation to the Gentiles and the glory of Your people Israel.’ (Luke 2)
Darkness is often used as a metaphor for the spiritual reality of sin and human ignorance. Those in darkness are thought to lack knowledge but it also refers to evil and willful blindness, as the rejection of light. This name points to the divine identity and purpose of Jesus. As he declared himself the ‘Light’, He was acknowledging himself as the source of spiritual light.
