Only a small remaining remnant of the 144,000 chosen to serve as assistant kings with Jesus go to heaven, the rest will be resurrected on earth during Christ's 1,000 year reign.
"And I saw, and, look! the Lamb standing upon the Mount Zion, and with him a hundred and forty-four thousand having his name and the name of his Father written on their foreheads. 2 And I heard a sound out of heaven as the sound of many waters and as the sound of loud thunder; and the sound that I heard was as of singers who accompany themselves on the harp playing on their harps. 3 And they are singing as if a new song before the throne and before the four living creatures and the elders; and no one was able to master that song but the hundred and forty-four thousand, who have been bought from the earth."
