The Watchtower contains an inconsistent view of the mediator. Christians generally believe that Jesus sacrifice for forgiveness of sins is offered to all mankind, and comes from his role as both Mediator and High Priest of the New Covenant. However the Watchtower view is quite unique in that it separates Jesus role for different classes;
- Mediator only for the 144,000
- High Priest on behalf of all
"He mediates the new covenant between God and those taken into the new covenant, the congregation of spiritual Israel. The total number of those who are finally and permanently sealed is revealed in Revelation 7:4-8 as 144,000." Insight on the Scriptures, Volume 2 p.362 Mediator
The Watchtower states that whilst Jesus is mediator for 144,000 only, those not under the new covenant will be blessed by Jesus through his role as their High Priest.
"Blessings to Mankind in General. While Jesus' mediatorship operates solely toward those in the new covenant, he is also God's High Priest and the Seed of Abraham. In fulfilling his duties in these latter two positions, he will bring blessings to others of mankind, for all the nations are to be blessed by means of Abraham's seed." Insight on the Scriptures, Volume 2p.362 Mediator
"Christ does not act as Mediator of the new covenant toward them, yet they benefit from this covenant through the work of God's Kingdom. Christ still acts toward them, however, as High Priest, through whom Jehovah can and does apply the ransom to the extent of their now being declared righteous as God's friends. (Compare James 2:23.)" Watchtower 1991 Feb 15 p.18
There is no Scriptural precedent to support the idea that the Mediator can be for a different group than that of the High Priest, or that the High Priest atoned for people not under covenant.
If the 144,000 are supposed to prefigure the kings and priests and also prefigure the entire nation of spiritual Israel, then who are they to rule?
The Watchtower parallels the Great Crowd with the Alien residents under the Law covenant.
"Since a number of these faithful foreigners, or alien residents, are viewed as foreshadowing the great crowd today, their situation is of interest to us.
Such ones were proselytes, dedicated worshipers of Jehovah under the Mosaic Law who were separated from the nations along with the Israelites. (Leviticus 24:22) They offered sacrifices, kept clear of false worship, and abstained from blood, just as the Israelites did." Watchtower 1995 Jul 1 p.17 "The Israel of God" and the "Great Crowd"
As the Great Crowd are said to be foreshadowed by the alien resident then it follows that the Great Crowd are included in the New Covenant in the same way alien residents were included in the Law Covenant.
