Isaac Wardell with BiFrostArts.com helpfully explains what we want of people singing together. We are not promoting "hymn sings" as Isaac mentions, but the heart of what Isaac is getting at where we sing together. And we want people to sing together regardless of style, genre, or song. Isaac ends the video by how songs bring different ages together, but we see the gospel as the unifier and cause of singing. The point of singing is the One who caused a song in us and caused us to come together as a "host (crowd) of voices" as Isaac mentions. The Bible's word "church" comes from the Greco-Roman time period referring to people who gather as part of their life for a certain reason and belief to learn and live by their convictions.
