Commentary to the 4th SUNDAY OF LENT – YEAR A
In today’s passage, John is inspired by an episode in the life of Jesus. He uses it to develop the central theme of the Christian message: the salvation given by Christ. He uses a biblical language: the dark–light contrast. In the Bible, darkness always has a negative connotation. It is the symbol of the dark power of evil, death, and destruction. Light represents an orientation towards God, the choice of good and life.
