I am also researching the 607BCE date and finding a lot of information from history website searches, just put in destruction of Jerusalem, as well as going to Jewishvirtuallibrary.org and look at the timeline as well as history. Since these are not "apostate" sites there is much information. However, the best information is on freeminds.org, under leftside column "Click and Go", then select Watchtower Doctrines, then select various options: Change of 606 to 607, Dates & Watchtower, Gentile Times, etc. especially read the letters under Gentile Times site. Look at afcministry.com, Jehovah's Witness section, and article on 586 or 607 BCE.
The search of WT CD under Jerusalem and 607 brings up only couple WT and basically admits everyone is saying 586/587BCE but WT only takes the bible not other sources. Ray Franz book Crisis of Conscience explains why he wrote the Aid Book on Chronology as a defense which does not support the 607 date just manipulates why everyone else is wrong.
Looks like a dog, barks like a dog, smells like a dog, wags tail like a dog, but it is a cat (per the society).
No matter how much you read you see the dates are correct( 586/587 BCE) but you are told it is 607BCE so just accept it because it is from the GB as Gods Word. Like the rest of the JW's on this site it is not easy but education is wonderful, read and reason with your mind and heart, and trust in Jehovah and keep in prayer for guidance, as it gets easier each day to accept that you do have a mind guided by God.
To the brothers worried how spouse will react, keep it open that you too love God Jehovah and are in prayer for direction and that your love is growing all the more for God and your spouse, this will keep in their minds that you love Jehovah and them as well and help overcome their fears that you dont. Keep Jehovah alive in your discussion and that you are still very interested in a relationship with God. I know we are all told to stay away from apostate literature but the two Ray Franz books are a must, there is so much love expressed and not trying to tear down JWs. Please get copies, hide them if you must, but read them, you will find you are not crazy for thinking like you are. My prayers are with you all.
Peace,
Sheri
