This clip is from the last 8 minutes of the True God's Day Celebration and was not in the original plan. During the ceremony Hyung Jin Nim realized he should be sitting in True Father's thrown as his appointed heir instead of humbly standing to the side as members bowed. He declared that this was a big mistake on his part and that Father asked that the bows be done again with the King and Queen sitting in their proper position.
At the Blessing service Hyung Jin Nim explained more about the mistake and implored us all to sit (stand) in our proper positions as God's Blessed children.
This is a great lesson from our King.
