For The Church of Jesus Christ of Latter-day Saints' Christmas service initiative, "Light the World," Monica Scott Music posted a video of children dressing up in nativity costumes with children singing "Away in a Manger" in the background.

Dec. 1 marks the beginning of The Church of Jesus Christ of Latter-day Saints' monthlong "Light the World" Christmas initiative. To celebrate, several UTubers posted videos online to share their light.

The Piano Gal, Sara Arkell, shared the story of Matt and Amber from YouTube channel "Matt and Amber Plus 3," who found out on Christmas Eve of 2013 that their baby boy would be stillborn.

In the video Arkell sings and plays the song "Where Are You, Christmas?" from the 2000 live-action film "How the Grinch Stole Christmas."

The Five Strings sibling musical team posted a video cover of "Do You Hear What I Hear?"

The video features a lighted treasure chest, candles and a large porcelain nativity. YouTubers Brooklyn and Bailey McKnight make an appearance.

Firefly, a group of sisters who sing country music, covered Alabama's "Angels Among Us."
