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.
Ezekiel 10:1-4
1
Then I looked, and see, in the expanse that was over the head of the cherubim there appeared above them as it were a sapphire stone, as the appearance of the likeness of a throne.
2
He spoke to the man clothed in linen, and said, Go in between the whirling [wheels], even under the cherub, and fill both your hands with coals of fire from between the cherubim, and scatter them over the city. He went in as I watched.
3
Now the cherubim stood on the right side of the house, when the man went in; and the cloud filled the inner court.
4
The glory of Yahweh mounted up from the cherub, [and stood] over the threshold of the house; and the house was filled with the cloud, and the court was full of the brightness of Yahweh's glory.
