Zechariah had a vision of Joshua wearing dirty clothes as he was standing by an angel
The dirty clothes were symbolic of sin and worldliness
The the clothes were made clean, representing the Jews return from captivity, removing the worldliness of Babylon, and once again becoming God's holy people.
To demonstrate this, I had 2 long strips of paper (from a roll) on the floor as my students arrived at class. I asked them to write as many sins as they could think of on the papers.
When we started the account of this vision, I put the two strips of paper on a student, using some pieces of tape, to make it look like clothing.
When Joshua clothing was cleansed, I slipped the "clothing" over the student's head, turned it over, and put it back on him with the clean side showing. This represented Joshua being cleansed and ready to officiate in the Temple.
It was a very effective.
Anything to get the students up and moving creates great discussion and creates an opportunity for personal application.
