The Watchtower (and their adherents) claim to be guided by the Spirit of Jehoover, so when they decide to disfellowship, it would be logical to think that this is God's decision (thats if they really are lead by the Spirit of Jehoover). But, the dilemma is, why do they need to give the one being disfellowshipped 7 days to appeal? If Jehoover wants this person out of Satans Organization, then why give him 7 days to appeal his (Jehoovers) decision? I thought Jehoovers decision was the be all and end all of everything? The book of Malachi says that he (Jehoover) never changes.
The Bible also says that Jehoover sees into the hearts, the minds of people, and that he tests these things out. If he does do this, then why would a repentant person need to write a letter to ask to join Satan's Organization again?
