The anointing by the holy spirit is the most awesome and marvelous thing that God has ever done. Jehovah was certainly not obligated to call even one insignificant little imperfect human into his realm and into his presence. That he would not only do that, but grant them the privilege of immortality and of ruling as kings is beyond human comprehension. The Devil's first lie was, besides his direct lie that disobedience would not result in death, was that God was holding something back from man. Satan implied that Jehovah didn't really trust humans and that Jehovah himself couldn't be trusted. In the light of that blasphemous slander, Jehovah's purpose to turn the rulership of his universe over to a bunch of reformed sinners is the most humiliating thing that Jehovah could possibly have done to Satan. The Devil apparently had ambitions to sit on God's throne and sought to usurp God with his cunning. God has throughly turned the tables on the demons by recruiting the dregs of humanity, and elevating them to a glory that not even the angels possess. So while the individuals who are called to that hope of themselves are not special, the calling is special.
So from the very beginning of the anointing, the demons have been keenly interested in resisting and perverting Jehovah's purpose. As one way to belittle the calling, through their apostate man of lawlessness the demons have long promoted the idea that all Christians are going to heaven to trample God's courtyards. The Bible though explains that it does not depend upon the one wishing, but rather it depends upon God's calling of an individual. Clearly God is very selective, even as Christ said that 'many are called but few are chosen.'
In the modern era of the restoration of primitive Christianity, the demons have obviously once again sought to insinuate themselves into the organization by pushing the idea that all Christians are anointed. The apostasy of one Ray Franz promoted that demonic doctrine. The demons apparently are also able to over reach some individuals in the organization to the extent of deluding them with a false sense that they too are anointed. My personal observations over the years has been that ones relatively new in the truth that are overcome with the idea of being anointed have all eventually left the truth, or had major phsycological problems. Thus the Devils game is to create confusion and dissension. The Watchtower has countered that demonic influence by reinforcing the uniqueness of the calling and creating an atmosphere within the organization that discourages new partakers.
The downside of that is that genuine newly anointed ones are also generally viewed with suspicion and distrust. But, that also serves God's purpose as well. Jesus was also rejected and viewed as a fraud and deceiver. So, in the body of Christ, some members suffer this, and others suffer that, so that within the totality of the body they fill up the full measure of the sufferings of the Christ as Paul said. Thus many of the older anointed ones went through various trials during the war years and in their confrontations with clergy and others. We don't face much of that now. The older anointed generally enjoyed the esteem of the brothers in the organization at least. Newly anointed ones though experience the contrast that Paul noted that existed even back then, namely, that some anointed are discreet in Christ, but others are looked upon as fools. Today the older anointed are strong, but we are weak, or at least viewed that way. In some sense, as Paul chided the Corinthians, some anointed live as if they have already begun ruling as kings. They 'are in good repute, but others are in dishonor.' (See 1 Corinthians 4:8-10) Also, Christ's parable of the master of the vineyard illustrates well how those who were hired early in the day, such as those anointed back in the 1919 period, would resent those who are hired at the last hour and yet receive the same wage. So Jesus foretold the schism that would exist between the older anointed ones and the newer ones.
But as for the anointing itself, John wrote as regards the anointing: "you do not need anyone to be teaching you; but, as the anointing from him is teaching you about all things, and is true, and is no lie..." So, there is no reason that anyone should need to consult a Watchtower magazine or anyone else to find out if they are anointed. Jehovah is the Great Communicator. He knows every language of man and angels. He can easily communicate via his spirit with anyone whom he calls and choses to participate in the heavenly calling. Each of those whom God communicates with know it. But that doesn't mean that a person can't lose their anointing. Obviously many have been unfaithful. / You Know
