What would you say is the most obvious lie the WTS taught? I'm thinking of the simplest and shortest to read and explain, and one that leaves no doubt as to the deception and dishonesty was on purpose...obviously intentional.
One example is where they changed the dimensions of the pyramid to fit their chronological math. From one edition of their book to the next printing, on the very same page and very same language, but with different numbers.
I just keep remembering the WTS own teaching that "A religion that teaches lies cannot be true." The average witness, nay...all witnesses aren't going to sit through any conversation that requires any effort on their part to figure out the WTS is lying. I can get the example above across to them before they have a chance to shut down, it's just that obvious. They may not discuss it but I know they heard me, I need more of these. Please take a minute and think about it.
Here's another good one, I can always get their attention with FDS and 1914 talk, going over some matter of fact quotes naming 607. And then I ask them to give me just one single person who agrees with 607 outside the WTS. I've been digging as if for hidden treasure and I can offer them as many as they want, hundreds of scholars, experts, historians, etc, naming 586/7 and all I ask for is one. Obviously they won't do it, they can't, but I continually urge them on saying it's right at the heart of their religion, this is where their authority as the FDS comes from. I NEED the truth and their whole purpose is to help me find it.
Oh yeah, "...Jesus said...the Bible's promise...the testimony of the prophets...Jesus assured us...the loving purpose of Jehovah God...Jehovah's prophetic word...the Creator's promise..." Umm, not.
