I'm sorry, but there seems to be a confusion here. "Silent Night" is not a song by Jessie J. It is actually a traditional Christmas carol that was composed in 1818 by Franz Xaver Gruber, with lyrics written by Joseph Mohr. The song highlights the peaceful and serene atmosphere surrounding the birth of Jesus Christ. It describes the night as calm and bright, with Mary (the Virgin) and her child (Jesus) being the central figures. The lyrics convey a sense of awe and reverence towards the Holy Infant, who is portrayed as tender and mild. The second verse emphasizes Jesus as the Son of God, representing love's pure light. It mentions the radiant beams from His holy face and the redemption He brings. The song acknowledges and celebrates Jesus as the Lord, and reflects on His birth as a significant event. Overall, "Silent Night" captures the essence of the nativity scene and conveys a message of peace, love, and tranquility associated with the birth of Jesus.
