I think it is certainly proper to observe the behavior of a certain group and make observations of that behavior and subject it to a standard. In this instance
the standard would be Jesus Christ and his teachings. (The FDS claims they represent God's Kingdom on Earth)
JesusChrist preached the kingdon of heaven/ JW's preach paradise Earth
JesusChrist gave his followers the hope to be WITH HIM in the HOUSE OF HIS FATHER/ JW's preach paradise Earth
Jesus told his followers he would go his way first and later they could follow/JW's teach paradise Earth
Jesus taught one faith, one hope, one baptism/JW's teach teach two hopes, two destinies, two classes of people
There are many other differences, but the above alone suggests to me that the JW teaching/doctrine-- whatever their FEELINGS may be---- is wholly contrary
to Christianity--- the discipleship of Christ, the drinking of his cup, the bearing of his cross, the surrender of the flesh for the promise of the spirit.
To inherit the kingdom of heaven one has to die, just as Christ did. The JW teaching and carrot has been that YOU DID NOT HAVE TO DIE!!! No, indeed,
you could by-pass the cup that Christ himself had to drink, and waltz right into paradise EARTH. And millions have reached out for this carrot and they have
ended up disillusioned. In the process they have missed out on the relationship that could have given them the most joy, the relationship of Sonship with the Father.
This relationship is denied them by their leaders. So the WT leaders and the JW ORG as a whole are ANTI-CHRIST for they deny his place, his power, and
his promise. That is not a judgement, but an observable and quantifiable fact.
