About the year 96 C.E., the aged apostle John was given a vision of these who go through the “great tribulation” in company with the “remnant” of spiritual Israel.

So right away I said to him: ‘My lord, you are the one that knows.’ And he said to me: ‘These are the ones that come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb.

Revelation 7:9, 10, 13-17.

34. Where do those of the “great crowd” expect to enjoy everlasting life, and what acknowledgment do they make of God and of his Lamb?

³⁴ So the “great crowd” does not expect to go to heaven even after surviving the “great tribulation.” Those of the “great crowd” expect the Lamb of God to shepherd them here on earth after the “great tribulation” and guide them to everlasting life in a Paradise earth. They acknowledge the enthroned God of heaven as the Universal Sovereign over all creation. They acknowledge the Messiah Jesus as “the Lamb of God that takes away the sin of the world” and admit that they owe their salvation to God through his once “slaughtered” Lamb and, by faith and obedience, “they have washed their robes and made them white in the blood of the Lamb.”
