In the Witness mind faith in the Organization is the same as faith in God, leaving "Jehovah's Organization" is the same as leaving Jehovah himself. Doubting the organization is the same as doubting Jehovah. So before bringing up damaging information it is helpful to separate the Witnesses faith in God (which we want them to keep) from faith in the WT Organization (which we want them to loose)
Here are some questions which can be brought up using a 1970 Watchtower arcticle in which while speaking of other groups they contradict the above principals which they usually drum into JW minds.
Is questioning a religious organization that claims to represent God the same as questioning God?
Is doubting a religious organization that claims to represent God the same as doubting God?
Where should we place our ultimate faith: in a religious organization or in God?
To whom do we owe the greater loyaly to a religious organization or God?
Does John 6:68 refer to a church organization or to a person (Jesus Christ). Should a religious organizaion take a passage applied to Jesus Christ and apply it to itself?
The above questions can be brought up using the January 15, 1970 Watchtower p. 37-40 which contains an arcticle titled:
"Which Comes First- Your Church or God?"
"The "first man" represents the believers who remain faithful to their church out of loyalty to the religion they were brought to believe in. Thier attitude is: Right or wrong, it is my religion! Is that the way you feel? If so, you are certainly a loyal person. But to whom do you owe the greater loyalty-to your church, or to God? With so much disbelief rife throughout the earth, you are to be commended for maintaining your faith, but where should your faith be placed-in a religious organization, or in God?" p.37
"The "second man" mentioned in the Nouvel Observateur represents those Catholics and Protestants who stay with their church because they do not know where else to go. They havebeen taught that their church represents God, and they do not want to turn away from him. They disapprove of many church practices or doctrines, but they hope to reform their church from within. Typical of these are the 744 French Catholics who, in November 1968, sent a long open letter to the pope. In it they stated: "Today the Christian needs to live in a 'true' Church . . . Therefore all that is false, contrary to the Gospel and scandalous within the Church today wounds the Christian." Then followed a long list of grievances against the Catholic Church and it current teachings and practices. Yet, toward the end, these catholics expressed their unconditional adherence to their church by alluding to John 6:68 and stating: "Who could we go to? In her [the Roman Catholic Church] we find the One who has words of eternal life." p.39
I beileve that this Watchtower arcticle can with a few simple questions be used effectively to separate the witnesses "Loyalty to God" from "Loyalty to the Organization". The Issue of faith in a religious organization being separte from faith in God is addressed nicely. Also issues of "where else to go" and the misappication of John 6:68 from Christ to a "church" or "organization" can be very effectively brought up using this arcticle.
In an earlier post the follwing was given by a former witness as some of the reasons for staying in the Watchtower Organization.
"Obstacles/hinderances: Loyalty. Thinking that there was no where else to go. Fear of the unknown. Believing God and the Watchtower were inseperable. Believing we would lose Gods protective barrier and bring death on our family (Like Job) if we left."
I believe that the above article can be used effectively and non-offensively to deal with these common issues.
