AC 6144 - why despair is the last of temptation

AC 6144
There are many reasons why despair is the last of desolation and of temptation....

Despair causes those who feel it to acknowledge
in an effectual and feeling manner
that there is nothing of truth and good from themselves,
and that from themselves they are condemned;
but that they are delivered from condemnation by the Lord;
and that salvation flows in by means of truth and good.

Despair also causes them to feel the happiness of life
which is from the Lord;
for when they come out of that state,
they are like those who have been condemned to death,
and are set free from prison.
Moreover by means of desolations and temptations,
states contrary to heavenly life are felt,
the result of which is the implantation
of a sense and perception of the satisfaction and happiness of heavenly life;
for a sense and perception of what is satisfying and happy
is impossible without comparison and the opposites.
To the end therefore that full comparisons may be made,
desolations and temptations are brought to their utmost, that is, to despair.
