My top ten:
1. Has the Watchtower ever taught anything that was scripturally incorrect?
2. Is it possible that they are teaching things that are scripturally incorrect today?
3. Since the Watchtower has received new light about the generation that saw 1914, does this mean that those that those Jehovah's Witnesses that were disfellowshiped for the same view that the organization NOW has before they taught it will now automatically be reinstated?
4. Why are you called, "Jehovah's Witnesses" and not "Christians"? Since Jehovah's Witnesses appeal to Isa 43:12; 44:8 for scriptural support that they should be called, "Jehovah's Witnesses" then what was the "new name" prophesied in Isa 62:2? Can't be "Jehovah's Witnesses", for God already used it 20 chapters earlier. Could the new name be "Christian" after our savior "Christ"?
5. If the name "Jehovah" is so important, then why does Acts 4:12 say, "There is salvation in no one else; for there is no other name [v10 Jesus Christ] under heaven that has been given among men, by which we must be saved"? Would this not have been the logical place for God to have used the name "YHWH"?
6. Jn 1:3 says that Jesus created "all things", but in Isa 44:24, God says that he "by myself" created the heavens and the earth and asks the question "Who was with me?" when the heavens and the earth were created. How can this be since if Jesus was created by God, then he would have been with God when everything else was created?
7. If the spirit of a man has no existence apart from the body, why does Stephen just before his death in Acts 7:59, pray to Jesus to "receive my spirit"? How could Jesus receive Stephen's spirit if a man's spirit ceases to exist when the body dies?
8. If there are 144,000 spirit anointed people who have a heavenly hope, and a great crowd of people who have another hope of everlasting life on paradise earth, why does Paul say that there is only ONE hope (Eph 4:4), instead of two?
9. In Rev 19:1, where does it say that the "great crowd" will be?
10. To what was Jesus referring to by the term "this temple" in Jn 2:18- 19?
