Covetousness
Put off the Natural Man, and Come Off Conqueror
Thou shalt not covet



Play hot potato with a candy bar.  Tell students that you won't tell them if it is good or bad to get the candy bar.  Pass the candy bar around in a circle when the music is playing and when the music stops, the person with the candy bar is it.  Continue on with your lesson making the one that got the candy bar it look like they got it.  Then turn to the student who got the candy bar and ask them to give it to someone else.  They won't want to.  Talk about coveting things you already have and things you wish you had.
