Jehovah's Witnesses believe that the leadership of their organization represents God's faithful slave based on the parable of the faithful/unfaithful slave. They believe that God appointed a slave in these final days before armageddon. Is this interpretation correct?
It is clear that the faithful and unfaithful servant parable has nothing to do with the final days before armageddon.
Why? Because Jehovah's Witnesses believe that Jehovah God will destroy all the wicked people on the planet but Jehovah's Witnesses will remain untouched.
If this is true, why is it that the unfaithful slave is not destroyed with all the wicked ones? Jesus says, the unfaithful slave will be assigned a place with the hypocrites. He is not executed with the others.
Clearly this parable has nothing to do with the 'time of the end', this 'doomed system of things', 'armageddon', etc. In fact if you read the parable, in Matthew 24:45-51, you will see that it's meaning is unknown.
According to the Bible, Christians do not run ahead of the teachings of Jesus. 2 John 1:9-11
