The human mind is so delicate and so complex that only its Maker
can know it wholly.
Each mind is so different, actuated by such different
motives, controlled by such different circumstances, influenced by such
different sufferings, no one can know all the influences that have gone to make
up a personality.
Therefore, it is impossible to judge wholly that personality
and what that person is going through.
But God (the one of your own
understanding) knows that person wholly and He can change it.
Leave to God the
unraveling of the puzzles of personality. And leave it to God to teach you the
proper understanding.
