'O Holy Night' is one of the most beloved carols of the season, and YouTube is rife with singers and musicians offering their take on it. I just watched Rhema Marvanne's effort, back in 2009 when she was 7, and I got goosebumps. Her voice is that powerful, her range that broad. And reading that Rhema's mom Wendi died from ovarian cancer only the year before leads me to believe the strength with which she sings this song of worship comes from somewhere deep.
Over four years since this video was put on YouTube, God is still using it for His good. Make sure to watch to the end because it goes really big.
