Did not actually convert but did come pretty close to converting after 6 years of study with my wife and other witnesses. They could very easily use the Bible to refute some of my personal beliefs or at the least some of my understandings of the doctrines I accepted. They alone (seemingly) taught that Jesus was not born on Dec 25 and the idea that many of their doctrines did seem to line up more closely with the Bible than the doctrines I came to believe in. They alone seem peaceful in that they wanted no involvement in the military and they seemed to rely on God more by not preaching about politics or even participating in government. They were not nationalistic like so many other churches were as they believed more in a worldwide brotherhood which I found appealing. By claiming these were the things found in early Christianity they claimed that they were the closest to the original Christians both in belief and practice.
What they don't tell you is their false prophesying in the past concerning the years 1914, 1925, and 1975 for example. They also fail to tell you about their past teachings concerning the years 1799, 1874, and 1914 and how they refined them due to the passage of time rendering them false and not by some divine revelation. That fact alone puts them more in the camp of other preachers and religious institutions that falsely prophesy only to later make up more bullshit to cover up their previous bullshit.
How can anyone take this religion seriously once it has been revealed that back during the time of Jesus' inspection the Bible Students were teaching false prophesy and various ludicrous teachings like Michael the Archangel being the Pope, the Leviathan being a steam locomotive, the distance of 1600 furlongs in the Bible describing the distance between Scranton, PA and the Watchtower headquarters in NY, and that the great pyramid of Giza predicting 1914? Especially when the pyramid teaching was later debunked as satanic by the Watchtower society sometime later. None of this is ever mentioned during any Bible study and most JW's are woefully ignorant of their own history.
Their excuse that they were refining their teachings and correcting their errors does not hold much water as at best many Christians I come across also refine their beliefs (some more dramatically than others) upon the presence of greater evidence or due to a more intense Bible study. So, no special award to the witnesses for that one. Also, considering that their teachings concerning pyramidology, Michael the Archangel being the Pope, and the Leviathan being a steam locomotive were truly unique to them they cannot claim (as they often try) that they simply inherited their errorneous teachings from apostate christendom that they had to later refine after they learned the truth about them as they reason for why they originally celebrated Christmas.
