164. As has been stated, man's proprium is nothing but evil, and when presented to view is terribly ugly; but when charity and innocence are instilled into the proprium by the Lord it looks fine and attractive, as stated in 154. The charity and innocence not only excuse the proprium, that is, a person's evil and falsity, but also virtually do away with it, as anyone may see in the case of young children. When they love one another and their parents, and at the same time a childlike innocence is evident, evil and false traits at such times not only go unnoticed but are even pleasing. From this it can be seen that nobody is allowed into heaven unless he has some measure of innocence in him, as the Lord said,

Let the young children come to Me and do not hinder them; of such is the kingdom of God. Truly I say to you, Whoever has not received the kingdom of God like a young child will not enter into it. Taking them up therefore into His arms, He laid His hands upon them, and blessed them. Mark 10:14-16.

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.
