*** re chap. 20 pp. 124-125 par. 17 A Multitudinous Great Crowd ***
From the time of the apostle John and on into the Lord’s day, anointed Christians were puzzled as to the identity of the great crowd. It is fitting, then, that one of the 24 elders, representing anointed ones already in heaven, should stir John’s thinking by raising a pertinent question. “And in response one of the elders said to me: ‘These who are dressed in the white robes, who are they and where did they come from?’ So right away I said to him: ‘My lord, you are the one that knows.’” (Revelation 7:13, 14a) Yes, that elder could locate the answer and give it to John. This suggests that resurrected ones of the 24-elders group may be involved in the communicating of divine truths today. For their part, those of the John class on earth got to learn the identity of the great crowd by closely observing what Jehovah was performing in their midst. They were quick to appreciate the dazzling flash of divine light that emblazoned the theocratic firmament in 1935, at Jehovah’s due time.
I remember the Bible saying somewhere that we shouldn't communicate with the dead?
When they say to you, "Consult the mediums and the spiritists who whisper and mutter," should not a people consult their God? Should they consult the dead on behalf of the living? (Isaiah 8:19)
