Supplies:
Large White heart balloon, bright flashlight, light stick (the kind you bend and it glows)
Prep.: Blow the balloon up but not tight. Put the light stick inside the balloon far enough that the base of the light stick acts as a plug for the inflated balloon. The balloon has to be soft enough to bend when it is time to break the light stick.
The lesson:
When God spoke to Adam, Moses, Noah, Jerimiah, Daniel, Abraham - all of the people he spoke to in the old testament, he spoke to them. When an angel came to them, the angel spoke to them. When the Holy Spirit spoke to some one, the spoke and were gone. (During this part of the story, I have the lights very dim with the flashlight shining on the balloon.
Turn the flash light off - the room is almost dark.
At pentecost, for the first time, the Holy Spirit dwelt inside people!
With this statement, I bend the balloon and break the lightstick and the balloon glows.
Instead of God visiting from the outside in, He now lives on the inside and it shows to the outside world.
Point:
I use this to illustrate how God spoke to the 'saints of old', does not speak to us in the same manner but rather, because of the death, burial and resurection of Jesus Christ, He can live in our heart and be there all of the time.
