AC 5173 - Cause & Endeavor; AC 5177 - Worry About the Future

AC 5173 [2, 3] - Endeavor

. . . the truth is that in all and each of the things
in nature and her three kingdoms
there is an inward active force from the spiritual world;
and unless this were so,
nothing whatever in the natural world
could act as cause and effect,
and consequently nothing could be produced.

. . . it is according to laws known in the learned world
that when endeavor ceases, motion ceases,
and also that everything of determination
is in endeavor,
and that in motion there is nothing real except endeavor.
It is clear that this force or endeavor in action or motion
is the spiritual in the natural;
for to think and will is spiritual,
and to act and be moved is natural.

AC 5177 - Worry About the Future

Those who have been very solicitous about the future . . .
when confirmed by act,
greatly dulls and retards the influx of spiritual life;
for they attribute to themselves
that which is of the Divine Providence;
and those who do this
obstruct the influx,
and take away from themselves the life of good and truth.
