There are lots of reasons to talk about being “ONE” in churches. There are ideas of being the body of Christ and being unified in our mission to take the love of Christ to the world. If you are in youth ministry no doubt you have taught a mission on unity before.
I found this video today that just begs to be used as an object lesson. It is an internet project from last year that takes over 1000 singers from around the world and has them post videos on YouTube and then a team combined all of the parts into one multivoice choir to make a rather dramatic piece of music. Even a short clip of this would be great to show as an object lesson.
From the description: The 2011 Virtual Choir video features 2052 performances of ‘Sleep’ from 1752 singers in 58 countries, individually recorded and uploaded to YouTube between September 2010 and January 2011
