Christmas is a time to celebrate the birth of Jesus, the son of God who is believed to have been born on December 25th, in the year 0. His birth is seen as a miracle, a sign of hope, and a symbol of the love and mercy of God. Jesus is considered to be the light of the world, and so we celebrate his birth with the lighting of candles and the exchanging of gifts. The day has become a time of joy and generosity, where we come together to celebrate the birth of our savior.
