AC 6388
. . . (those) who are in genuine mutual love
are in their delight and bliss
when they are benefiting the neighbor,
for they desire nothing more.
This delight and bliss are what is meant by "hire" in the Word;
for the delight and bliss is itself the reward;
and in the other life this becomes the joy and happiness
which are in heaven, thus it becomes heaven to them.
For when they who are in this love perform uses,
and do good to others,
they are in such joy and happiness
that then for the first time
they seem to themselves to be in heaven;
this is given them by the Lord,
to everyone according to the uses he performs.
But the happiness vanishes as soon as they think of reward,
for being in the reward itself,
thought about reward renders that love impure, and perverts it;
the reason of which is
that they are then thinking about themselves,
and not about the neighbor,
that is, about making themselves happy,
and not others,
except Insofar as it affects themselves.

AC 6392
. . . (those) who are led by the Lord
desire nothing more than to do good works,
and that nothing is further than their thought
than of meriting by them. This is in the new will,
which is given by the Lord
to those who are being regenerated,
for this will is the will of the Lord in the person.
