IMO, the keepers are:
Worldwide Security Under the "Prince of Peace" (1986) Grey - "Likewise, the Greater Moses, Jesus Christ, is not the Mediator between
Jehovah God and all mankind. He is the Mediator between his heavenly
Father, Jehovah God, and the nation of spiritual Israel, which is
limited to only 144,000 members."
The Truth That Leads to Eternal Life (1968) - And he warned: "I know enough of what is going on to assure you that, in fifteen years from today this world is going to be too dangerous to live in."
"By 1975 civil disorder, anarchy, military dictatorships, runaway
inflation, transportation breakdowns and chaotic unrest will be the
order of the day in many of the hungry nations."
The Nations Shall Know That I Am Jehovah (1971) - "Shortly, within our twentieth century, the "battle in the day of
Jehovah" will begin against the modern antitype of Jerusalem,
Christendom."
