As Splash said, this is taken from their website:
What Are Jesus’ “Belongings”?
Jesus said: “All authority has been given me in heaven and on the earth.” (Matthew 28:18) Jesus’ “belongings” thus include more than just his earthly interests. They include the Messianic Kingdom.—Philippians 2:9-11.
Consequently, Jesus will reward “the faithful and discreet slave” by resurrecting the individual members of that group to heavenly life and by giving them royal authority over all Christ’s belongings in heaven and on earth. This is the same reward promised to all faithful anointed Christians.—Luke 22:28-30; Revelation 20:6.
You can see:
1. Are they implying that the current GB 2.0 have to die to get resurrected and they their belongings? or are they talking about Rutheford and Co., or? or? or? (How convoluted this is)
2. Even as they say, all will have Christ's belongings, the doctrine in question is just talking about the Slave, NOT others.
Another thing, the Slave receives all the belonging because he gave food at the proper time. What food did the others gave?
The GB appoints Christ's belongings whoever they want.
