3. According to Daniel 7:27, who also are brought into that indefinitely lasting kingdom?

³ That kingdom has brought into it later on in this “time of the end” 144,000 spirit-begotten disciples of Christ. Just as Daniel 7:27 foretold: “The kingdom and the rulership and the grandeur of the kingdoms under all the heavens were given to the people who are the holy ones of the Supreme One. Their kingdom is an indefinitely lasting kingdom, and all the rulerships will serve and obey even them.”​—Dan. 12:4; Rev. 14:1-3; 20:4, 6.

Accordingly, the “great crowd” observes that, 63 years after Pentecost, Christ Jesus was still encouraging his spirit-begotten disciples to look forward to that kingdom, saying: “To the one that conquers I will grant to sit down with me on my throne, even as I conquered and sat down with my Father on his throne.” (Rev. 3:21) They had yet to inherit that coming heavenly kingdom as “heirs indeed of God, but joint heirs with Christ.” (Rom. 8:17) Jesus Christ is the main Heir of God, and his disciples are minor heirs.​—Heb. 1:1, 2.

6. According to 2 Peter 1:10, 11, were the spirit-begotten disciples already in that kingdom or yet to enter into it?

⁶ So the Kingdom of which those spirit-begotten disciples on earth were “joint heirs with Christ” is not something in which they had been since the outpouring of holy spirit at Pentecost of 33 C.E. For that reason the apostle Peter, writing his second letter about 64 C.E., or 30 years after Pentecost, gave his fellow Christians this admonition: “If you keep on doing these things you will by no means ever fail. In fact, thus there will be richly supplied to you the entrance into the everlasting kingdom of our Lord and Savior Jesus Christ.”​—2 Pet. 1:10, 11.

7. By means of what do they have that entrance into the kingdom supplied to them, and so what temporary relationship to Jesus Christ passes away?

⁷ In God’s due time the 144,000 joint heirs with Christ are richly supplied that entrance into the heavenly kingdom by means of the “first resurrection.” Then they will no longer be the spirit-begotten subjects on earth under “the Son of [God’s] love.” That temporary relationship with the glorified Jesus Christ will be gone forever. They will be the heavenly immortal, incorruptible kings with him. (2 Tim. 2:11, 12; Rev. 20:4, 6) This means that the temporary subject state that applied to them since Pentecost of 33 C.E. and while they were yet in the flesh on earth will have passed forever. (Col. 1:13) For having lived clean and faithful lives on earth, they inherit “the kingdom of the Christ and of God.”​—Eph. 5:5.
