AC 933, 935 - alternating states; AC 925 - the Lord's kingdom

AC 933 [4]
. . . when he (a person) is in corporeal and worldly things,
he is absent and remote from internal things,
so that he not only takes no thought about them,
but feels in himself cold at the thought of them;
but that when corporeal and worldly things are quiescent,
he is in faith and charity.
He may also know from experience that these states alternate,
and that therefore
when corporeal and worldly things begin to be in excess
and to want to rule,
he comes into straits and temptations,
until he is reduced into such a state
that the external person becomes compliant to the internal,
a compliance it can never render
until it is quiescent and as it were nothing.

AC 935 [2]
That there are alternations with the regenerate person -
now no charity, and now some charity -
is clearly evident for the reason that in everyone,
even when regenerated,
there is nothing but evil,
and everything good is the Lord's alone.
And since there is nothing but evil in him,
he cannot but undergo alternations
and now be as it were in summer, that is, in charity,
and now in winter, that is, in no charity.
Such alternations exist in order
that a person may be perfected more and more,
and thus be rendered more and more happy,
and they take place with the regenerate person
not only while he lives in the body,
but also when he comes into the other life,
for without alternations as of summer and winter as to what is of his will,
and as of day and night as to what is of his understanding,
he cannot possibly be perfected and rendered more happy;
but in the other life
these alternations are like those
of summer and winter in the temperate zones,
and those of day and night in springtime.

AC 925 [3]
. . . the state of the Lord's kingdom is a state of peace,
and in a state of peace
there come forth all the happy states
that result from love and faith in the Lord.
