Hi, thanks for posting...your post brought back memories.
Have you read Ray Franz Crises of Conscience? If not, please take time to do so. It set me free, at last. I was in the same position as you, undecided. What if they really were the Faithful Slave? Well, the answer lies in the Bible. Deauteronomy says that if a prophet speaks in the name of God, and that word does not come true then we should not believe the prophet. Jesus said Beware of False Prophets. Do the Watchtower/Governing Body claim to be prophets?
Yes.
Watchtower of 1972 April 1. Under the heading 'They shall know that a prophet was among them' , we read: People today can view the creative works. They have at hand the Bible, but it is little read or understood. So, does Jehovah have a prophet to help them, to warn them of dangers and to declare things to come? IDENTIFYING THE "PROPHET" These questions can be answered in the affirmative. Who is this prophet? ... This "prophet" was not one man, but was a body of men and women. It was the small group of footstep followers of Jesus Christ, known at that time as International Bible Students. Today they are known as Jehovah's Christian witnesses. ... Of course, it is easy to say that this group acts as a "prophet" of God. It is another thing to prove it. The only way that this can be done is to review the record..."
So you see they are asking you to review their record. What is their record?
Check out freeminds to see a comprehensive list of all Watchtower false prophecy. You cant argue against this. They claim to be prophets...but they are not! Who can argue against that? I challenge anyone to argue against it.
