If i may add something going of what i was taught when i was with the JWs...
I was taught that only 144,000 JWs will go to heaven to serve Jehovah and , there is no possibility that anyone else has a heavenly hope. we were told that we will not go to heaven. i was taught that only those who did Jehovah's will would live forever on a paradise earth and all other people will be destroyed in the battle of Armageddon. The only hope that others have is to join the WT and be counted among the number of the great crowd and serve Jehovah in the outer courts of the earth.
The question is, is the Great Crowd really confined to this earth with no heavenly hope? According to some interpretation, the Book of Revelation places the 144,000 in heaven and the great crowd on earth. The 144,000 is mentioned only twice in all of scripture (Rev 7:1-8, 14: 1-5), but the great crowd is mentioned three times in the Book of Revelation (Rev 7:9, 19:1, 19:6). Two Greek words are used to differentiate between the sanctuary, where the 144,000 are said to dwell, and the outer courts of the temple, where the great crowd supposedly resides.
Unlike the word hieron, which doesn’t appear in the book of Revelation, naos appears 40 times in the New Testament and 13 times in Revelation alone. We’ll look at just a few examples and then make comments.
REV 7:15- “For this reason, they are before the throne of God; and they serve Him day and night in His temple; and He who sits on the throne will spread His tabernacle over them. In other words, this verse puts the great crowd in the sanctuary of God’s temple.
REV 11:1-2- Then there was given me a measuring rod like a staff; and someone said, “Get up and measure the temple of God and the altar, and those who worship in it. “Leave out the court which is outside the temple and do not measure it, for it has been given to the nations; and they will tread under foot the holy city for forty-two months.
This verse makes a distinction between the outer courts and the temple proper. As we can see, God is only interested in the sanctuary and those who worship in it and not the outer courts.
REV 11: 19- And the temple of God which is in heaven was opened; and the ark of His covenant appeared in His temple, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm.
If verse two of this same chapter makes a distinction between the naos and the outer courts, and verse nineteen tells us that the naos is in heaven, where do we get the idea that the great crowd is in the outer courts? We cannot emphasize enough the fact that the word hieron is never used in the book of Revelation! The context always refers to a heavenly scene.
If this isn’t enough, there is one passage in in Revelation that specifically states that the great crowd is in heaven.
REV 19:1- After these things I heard what was as a loud voice of a great crowd in heaven.
There is no mistaking where this verse places the great crowd. IN HEAVEN
