Hi bobld!
I also disagree with the WBTS teaching about Jesus Christ coming back to establish his Kingdom in 1914! Anyone who believes that is crazy! However, I disagree with you in regards to Rev 1:7 where you believe that those that pierced Jesus are ALL who did not believe in him. I believe myself that this is mentioned in relation to Mathew 24 where Jesus clearly states in verse 30 that 'they will see the son of man coming on the clouds'. What Jesus does in verse 34 in make it very clear that his return is something that will be witnessed by 'THIS GENERATION' ie, the one that is with him at that time. This would include the ones that pierced his side. Those present at his death would also be part of the generation that was with him at that time. If that is the case, then that would mean that we would have to re-assess our understanding of the meaning of 'every eye shall see him'. Is it not possible that this could be a figure of speech that Jesus is using in order to describe his return in another way that we have completely misunderstood? You see, if Jesus promised the generation that was with him that they would see his return, then logically speaking, Jesus would have been pointing to something that would have happened almost immediately following his death and resurrection. The only thing that did happen after his resurrection was the outpouring of the Holy Spirit on his people!/
Hope I don't cause any offense with my views. I'm just throwing out a few ideas here!
