Would Light make light?

The Twitter world is ablaze with jokes and mockery of Harold Camping.

My question is, should we joke about a subject as veracious and important as Christ's return?

Of course, we must proclaim the truth and be aware of false prophets as Scripture warrants (Matthew 7:15-23).

But should we make light of the situation? What is the Christ-like way to react - publicly or privately?

Chime in with your thoughts...
