Heavenly Joy's Source

As man was created to perform uses, and this is to love the neighbor, so all who come into heaven, however many there are, must do uses. All the delight and blessedness of these is according to uses and to the love of uses. Heavenly joy is from no other source. He who believes that such joy is possible in idleness is much deceived.

No idle person is tolerated even in hell. 

Those who are there are in workhouses and under a judge who imposes tasks on the prisoners that they must do daily. To those who do not do them neither food nor clothing is given, but they stand hungry and naked; thus are they compelled to work there. The difference is that in hell uses are done from fear, but in heaven from love; and fear does not give joy, but love does. Nevertheless it is proper to vary occupations in different ways in company with others, and these serve as recreations, which are also uses.

It has been granted me to see many things in heaven, many things in the world, and many things in the human body, and to consider at the same time their uses; and it has been revealed that every particular thing in them, both great and small, was created from use, in use, and for use; and that the part, in which the ultimate that is for use, ceases is separated as harmful and is cast out as condemned.

(Apocalypse Explained 1194:2 ~ Emanuel Swedenborg)
