Hey @StephaneLaliberte, I noticed you used a recent example of deception in your opening post. The existing Governing Body's lies and misleading statements might be the best examples we can use to wake friends up with, I think. There's no "light getting brighter" fallback that way.
Check out the September 2015 Broadcast, hosted by David Splane. At eight minutes in, you can catch Splane in a verifiable LIE:
For those who don't watch the segment, basically what's happening between 08:00-09:30 is, Splane makes the unique claim that in 1914, the anointed people (Rutherford, Franz, Henschel, et. al.) were the "only ones who saw these signs and understood them correctly." This, apparently, is used as a proof that these were God's people on earth back then.
However, a trip down WT lane will reveal that in 1914, the doctrine being taught was that Jesus' parousia had occurred in 1874 . Rutherford, Franz and Co. were NOT looking for Christ's presence since they believe he'd already arrived four decades prior! According to Zion's Watchtower, Christ had indisputably begun ruling as king in 1878. And this continued to be taught all the way until 1932.
You remember Rutherford's campaign slogan back in the 1920's? Come on everybody, say it with me in three, two, one...
"ADVERTISE, ADVERTISE, ADVERTISE."
And what was he advertising, exactly? ...That Jesus had already come in 1874 and had started ruling as king in 1878.
Now, for David Splane to go on JW Broadcasting over a century later and say that those WT Presidents "CORRECTLY UNDERSTOOD" the sign, we can deduce this is nothing but a bold faced lie. This goes beyond misleading the JW audience. It is a despicable coverup and a rewriting of history.
