TCR 734, 735, 736 - What Is Heavenly Joy?

TCR 734 [3]

It is the delight of doing something useful
to oneself and to others;
and the delight of use derives its essence
from love and its existence from wisdom.
The delight of use,
arising from love through wisdom,
is the life and soul of all heavenly joys.
There is in heaven most delightful association,
which exhilarates the minds of angels,
cheers their spirits,
gladdens their hearts and refreshes their bodies.
These pleasures, however, the angels feel
only after they have performed the uses
pertaining to their office and employment.
From these uses are derived the life and soul
of all their pleasures and delights;
but if you take away that life or soul
the subsidiary joys gradually lose their charm;
first they become unattractive,
then as it were of little account,
and finally they bring that feeling
of oppression and anxious care.

TCR 735 [5]

. . . happiness comes to every one
from the use he performs in his own vocation.

TCR 736 [3]

The Lord loves all,
and so wills good to all,
and good is the same thing as use.
As the Lord does good, or performs uses,
through the instrumentality of angels,
and, in the world, of men,
therefore, to those who faithfully perform uses
He communicates the love of use,
together with its reward, internal blessedness;
and this is eternal happiness.
