Gal. 4:26 calls it Jerusalem which is above.
This verse as do many others are a problem for the WT and others that look at such texts as if altitude or location is being discussed. What Paul was really discussing is their dependence on the Law covenant and how things would work out in such a Jerusalem that did not require it. He gave this illustration about it. 21Tell me, ye that desire to be under the law, do ye not hear the law? 22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. 23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. This promise was above such Law for this Jerusalem above would be based upon it. It would be superior to such Law that enslaved them and be like the freewoman that appeared to be barren but would bear more children than such Law keepers. This is explained like this: 26 But Jerusalem which is above is free, which is the mother of us all. 27 For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband. While some verses are interpreted with height or location in mind and that people will be selected to go to such a place I have not found any text that teaches this doctrine. The real point such verses make is that the place where all men will reside is a place blessed by and authorized by God and called heaven or heavenly by Jewish writers for such reasons. Such use of words reflects their custom and in similar texts can be shown like this:
Mt 11:11 Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he.
Lu 7:28 For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: but he that is least in the kingdom of God is greater than he.
What may look like location at first when we see words like heaven becomes nothing more that Jewish custom when God or a higher authority like something approved by God is being discussed.
