SD 4773m - heavenly joy consists of an active life of usefulness

SD 4773m  
. . . people at this day, do not know what heavenly joy is,
. . . but that they suppose it to consist in this,
that they should be cared for by angels and spirits,
and should thus breathe joy in idleness; and this to eternity.
That this is false, was shown them by the fact,
that there are no spirits and angels who have not been people:
Secondly, that in heaven,
it is not permitted to be served by others,
but to serve others;
and that mere joy in idleness,
vanishes away in a few hours or days, since it is without life.
Idleness at length wearies everyone . . ..
But . . . heavenly joy consists in an active life, thus in use;
and that according to the use they possess joy,
so that use is the subject of joy . . ..

Concerning the uses which angels perform,
and by virtue of which they perceive joy,
it was also said, that these are very numerous,
and more remarkable than a person ever believes.
Glorifying the Lord is not a use, but a recreation;
for [angels] glorify the Lord in every use.
This the Lord loves.
Their uses, also, are
(1) to be with people, to insinuate there goods and truths,
     and to turn aside evils and falsities.
(2) To instruct spirits who come from the world.
(3) To instruct infants.
(4) To awaken the dead,
      and to lead and inform those who are awakened.
(5) To watch over these, and, moreover,
      to attend to domestic duties there . . .
      besides other things innumerable.
In these things the angels take such joy as is indescribable:
for these things relate to mutual love,
or charity towards the neighbor.
