1. For Every 50 Dates that point to a date other than 607 BCE there are 2 Secular, non Jehovah's Witnesses Sources that point to it.
I see you tackled the one argument that I said was a wild goose chase. 607 is only a problem because JWs make a big deal of it when, in fact, it shouldn't even be part of the argument based on the future tense of Jesus' words, which ALSO shouldn't be part of the argument because it's a cherry-picked link between the "seven times" in Daniel 4 and "times" in Luke 21:24. This is a non-argument. The whole 1914 thing is a fabricated prophecy.
2. Jesus Apostles continued to be wrong on several things, and Jesus never corrected them.. Example Acts 1:6 , they were expecting the Kingdom to be restored to Israel at that very Time.
Of course he corrected them. At Acts 1:7, he said "It does not belong to you to know the times or seasons that the Father has placed in his own jurisdiction." How is that not a correction?
3. With in "Gods Organizations" there have always been Errors & Innacurate Prophesies. - Deuteronomy 18:22 "when a prophet speaks in the name of the LORD, if the word does not come to pass or come true, that is a word that the LORD has not spoken; the prophet has spoken it presumptuously. You need not be afraid of him." This scripture is spoken to Gods Chosen people, The Nation of Israel, which proves there were False Prophets amongst the Israelites, the same as there have been among The Organization. The Scripture does not say "The Israelites will no longer be gods chosen people, it says do not be afraid of him The False Prophet (Individually).
I'll hold back a little on this one. But, two things:
1. The new covenant is that God would teach people himself. Jer 31:33,34 is that new covenant: "“For this is the covenant that I will make with the house of Israel after those days,” declares Jehovah. “I will put my law within them, and in their heart I will write it. And I will become their God, and they will become my people.”" If God is writing his law within people's hearts, how would it be possible to write errors and inaccuracies? And they will no longer teach each one his neighbor and each one his brother, saying, ‘Know Jehovah!’ for they will all know me, from the least to the greatest of them,” declares Jehovah. “For I will forgive their error, and I will no longer remember their sin."
2. If any organization claims to have the truth, then that "truth" changes, and people are expelled, excommunicated, disfellowshipped for not believing their current version of truth, then how could that organization possibly be God's organization? This goes back to your first argument that Jesus never corrected the apostles. If that is true, then why would the organization dare to correct or throw out people who don't believe what comes from the organization as "truth"? Is the organization greater than Jesus?
