One
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.
John第17章:21-23
21
that they may all be one; even as you, Father, are in me, and I in you, that they also may be one in us; that the world may believe that you sent me.
22
The glory which you have given me, I have given to them; that they may be one, even as we are one;
23
I in them, and you in me, that they may be perfected into one; that the world may know that you sent me, and loved them, even as you loved me.
