It is important to remember that in the ancient mind, “heavens” referred to the skies and outer space, as well as the realm in which God dwells. So, when Revelation 21:1 refers to the new heavens, it is likely indicating that the entire universe will be created—a new earth, new skies, a new outer space.
Marami ang naniniwala na ang "langit" ay tumutukoy sa himpapawid at kalawakan, ganoon din sa kaharian na siyang tahanan ng Dios. Kung gayon, ang binabangit na bagong langit sa Pahayag 21:1 ay nagpapahiwatig na ang buong sangkalawakan ay muling lilikhain - isang bagong lupa, bagong himpapawid at bagong kalawakan.
