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.
Isaiah 12
1
In that day you will say, "I will give thanks to you, Yahweh; for though you were angry with me, your anger has turned away and you comfort me.
2
Behold, God is my salvation. I will trust, and will not be afraid; for Yah, Yahweh, is my strength and song; and he has become my salvation."
3
Therefore with joy you will draw water out of the wells of salvation.
4
In that day you will say, "Give thanks to Yahweh! Call on his name. Declare his doings among the peoples. Proclaim that his name is exalted!
5
Sing to Yahweh, for he has done excellent things! Let this be known in all the earth!
6
Cry aloud and shout, you inhabitant of Zion; for the Holy One of Israel is great in the midst of you!"
