Searcher, That is an interesting take that I had not considered before. I think the answer to who Jesus would leave in charge is quite simple. I am sure you have seen the scripture. In his own words at John 14:26- But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.
When I shared this scripture with my JW parents in an effort to help them realize that they do not need the "FDS" and that Jesus was clear who was in charge. They simply said they "do not believe that", I said "I was reading a scripture from Jesus own words", still "we don't believe that".
Of course, they insist on the having their FDS security blanket...ugh!
I am slightly tempted to email my JW father and say something like "I guess you were wrong by referring to the Evil Slave (100 plus time-no exageration) being responsible for taking me out of the org because now that the FDS realized that they could be attached to the reference of the Evil Slave it dissapears. Amazing how that works!
