A watcher if you believe the bible please consider the following verse -
Luke 21:8 He said: “Look out that you are not misled, for many will come on the basis of my name, saying, ‘I am he,’ and, ‘The due time is near.’ Do not go after them.
This is the first thing Jesus says when asked about the time of the end. So what is the 'good news' that JW's are preaching? Is it not 'the due time is near, come after us or be slaughtered by Jehovah'?
How many warnings did Jesus give about false prophets? Name a religion that has preached more false prophecy than JW's. If this is the time of the end and JW's are not false prophets then who is and on what basis?
I'm guessing you believe in the devil as well, if so ask yourself if you believe the devil controls the world and false religion, would it be too hard a task for him to get one of his false religions to preach a false message throughout his world?
In my opinion JW's exist because personality disorders like narcissism exist and because mind control is real.
