Emotions

This is the way it is with all emotions: fear, anger,
anticipation, dread, and so on. They are usually provoked
by some circumstance in our lives, but they are
your responses to and your interpretations of that event.
In other words, they reveal you. For example, if you get
an unexpected bill, it can provoke financial concerns.
But if you obsess and are chronically fearful about your
financial future, that fear reveals where you have put
your trust: you have put it in yourself rather than your
God. Your emotions reveal you.
