Something I considered doing on Sunday (only briefly since it would have taken far too long) was to "play telephone" with the congregation.  You remember that kids game - you whisper something to the person at the beginning and they continue to whisper what they thought they heard to the person next to them and so on throughout the group.  At the end you compare to see if what was finally heard comes close to what you started with.  Seemed like a decent way to introduce the idea of getting your information directly from the source (God speaking to us directly through His son).  It of course had a couple of shortfalls.  The time for such a message to get through the entire congregation for starters.  But more seriously, the comparison with biblical inspiration falls apart quickly.  In telephone there is no guiding of the Holy Spirit to direct what is said from one person to then next.  So I canned the exercise!   SMJ
