A company might have executives setting policy and strategy, engineers designing products, managers handling personnel and others handling various functions. They all do different things -- but if they're doing them with a shared underlying purpose, the company -- and the individuals in it -- will likely be successful. The Lord wants all human society to function in a similar way. We have different skills and individual loves, but if we all share a mutual love -- a love of serving others -- then society will function as one, will be a reflection of heaven and will be a good receptacle for the Lord's love. This can also happen within each of us, as we unify our talents and ideas around a central love. And in an abstract sense, it illustrates how a wide collection of varying ideas can be unified around a shared good intention. That is the kind of love pictured when “one” is used in the Bible, either as a specific number or in the sense of several people or objects “being one.” In more casual references -- when used to identify a specific person or object -- the meaning is relatively literal, and is connected to that person or object.

Heaven" and "heavens" are used many times in the Bible, with a couple of variations of meaning. Sometimes it is relatively literal, including times when the Lord is identified with it (“Our Father, who art in the heavens,” for instance), meaning heaven as the eternal home for people who chose to do what is good in this life and let the Lord lead them to a love of being good. In other references, particularly when it is paired with “earth” or other lesser ideas (“In the beginning God created the heavens and the earth,” for instance), “heaven” or “heavens” means our internal life as opposed to our external life. In a way, these two meanings are really the same. If you think about the importance of your deepest thoughts and feelings, you can see that they are the “real” you, much more so than your body is. The relationship between the spiritual world and the natural world is similar; the spiritual world is the “real” one, and controls the natural world the same way our thoughts and feeling control our actions. So in both cases, “heaven” describes a deeper reality that we will enter fully after we die.
