If the elders approach you and start asking questions to make you feel awkward, quietly asked them whose 8th year is spoken of at 2 Ki 24:12
(2 Kings 24:12) . . .At length Je‧hoi′a‧chin the king of Judah went out to the king of Babylon, he with his mother and his servants and his princes and his court officials; and the king of Babylon got to take him in the eighth year of his being king. . .
If they say the 8th year of Nebuchadnezzar, look puzzeled and say "oh you don't agree with the GB then." If they say Jehoiachin's say, "oh you don't agree with Jehovah's Witnesses (Ezekiel and Jeremiah) then."
Am doing a youtube to help make the issue clearer for everyone but basically you can blow them out of the water on their 1914 doctrine using the authority of God and pure science (maths) to trump them. It only takes 7 scriptures and what you find is they REFUSE to look at the scriptures cause it is SOOOO self evident.
