Present the parable about the talents (Matthew 25). Teach the kids about the value in using what we've been given to invest in others. Give them the $1 bills and challenge them to invest in someone else this Christmas season. Give a few ground rules...not able to use on immediate family, must be used by a certain date, etc. Challenge them to take the $1 bill and grow the money and then use it to invest in someone else this Christmas season. You'll be surprised at how kids rise to this challenge to minister to others. Have a date that the project must be wrapped up by and have kids share what they did with their $1.
Would the kids in your ministry rise to this challenge?!
