Webster's Dictionary defines "fickle" as "Not fixed or firm; liable
to change; unstable." Your emotions and how you feel are unstable and
liable to change. So, if you follow your feelings, then your life, your
choices, and your actions will sway like a tree in strong wind.
Because your feelings can be unstable, it is important not to follow
them exclusively. For example, there will probably be some days when you
don't feel like being nice to your spouse. If you follow your
feelings and act impulsively, then your marriage will have problems.
Because feelings are unstable and unpredictable, someone who lives based
on their feelings will also be unstable and unpredictable.
Indeed, (James 1:8) says that someone who
follows his feelings "is a double-minded man, unstable in all he does."
Instead of following our feelings, we need to follow God, for He is
the only source of true stability.
In (Matthew 7:24-27), Jesus says,
"Everyone who hears these words of mine and puts them into practice is
like a wise man who built his house on the rock. The rain came down, the
streams rose, and the winds blew and beat against that house; yet it did
not fall, because it had its foundation on the rock. But everyone
who hears these words of mine and does not put them into practice is
like a foolish man who built his house on sand. The rain came down, the
streams rose, and the winds blew and beat against that house, and it
fell with a great crash."
