"O Come All You Unfaithful" is written by Lisa Clow and Bob Kauflin and is the first track to be released from Sovereign Grace Music's forthcoming Christmas album, "Heaven has come". Here is information from the YouTube page, explaining the filming of the video:
This video contains people who are processing “O Come, All You Unfaithful,” most of them for the first time, in light of their own experiences. A stillborn child. A strained marriage. Feelings of shame. Legalism. Loss. Loneliness. Or simply having a heart that weeps with those who weep. We think seeing their responses as Lisa Clow sings communicates even more clearly that Jesus wasn’t born for people who have it all together. He was born for those who have nothing. “Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls. For my yoke is easy, and my burden is light.”” (Matthew 11.28–30, ESV) “She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” (Matthew 1.21, ESV) So come.
