Jesus described Heaven as having many rooms or dwellings (John 14:2-3). Like earthly cities or countries, heaven includes individual dwelling places: the plural “rooms”, not just the singular “place.” Heaven contains a permanent inheritance, an imperishable estate specifically reserved for us (1 Peter 1:4).
When we are in Heaven, we will welcome others into our dwelling places. Jesus speaks of the shrewd servant’s desire to use earthly resources so that “people will welcome me into their houses.” Then Jesus tells his followers to use “worldly wealth” (earthly resources) to “gain friends” (by making a difference in their lives on earth), “so that when it is gone [when life on earth is over] you will be welcomed into eternal dwellings” (Luke 16:9). Our “friends” in heaven appear to be those who we’ve touched in a significant way on earth. They will apparently have their own “eternal dwellings.” Luke 16:9 suggests these eternal dwelling places of friends could be places to fellowship and stay in as we move about the heavenly kingdom.
