For example, when I press, "Like" on Facebook, that witness goes out to my 1201 friends, in addition to the friends of the person witnessing. Think of the exponentially, explosive possibilities. I use the term, "witness," purposely as everything a Christian posts is a witness, a reflection of Christ in him or her.
Take this example, posted on my Facebook page this morning by a well-meaning Christian friend, and at this reading "liked" by two others. It was a picture of President Obama with a photo shopped "Hitler" mustache, and the caption, "Adolph Obama." It was in reference to Obamas perceived Gestapo tactics with regard to Healthcare.
Now suppose my well-meaning friend had paused a moment and thought, "Would Christ "share" or "like" this post? How will this reflect on my Christian witness?" Would he/she have shared this particular message? I think not. And I would feel similarly were it a caricature of George W. in reference to invading Iraq, or Romney and Bain Capital.
In other words every Cyberspace social media posting should be preceded by WWJD (What would Jesus do?). Or better yet, WJDD (What Jesus didn't do!). Oh, and to add a little levity to a weighty matter, click on the following link for a humorous, satirical, lighthearted look at WJDD:
