The key word here is "expectation.” It is a future thing. Sucking resentment, or any flavor of negative emotionality, out of events in the future or projecting undesirable outcomes that “might” happen, feeds the lower nature (ego) the negative energy it needs. This is extremely dangerous.
It is every bit as dangerous as reacting with anger to current or past events.
Anyone using the spiritual procedure delineated through the Twelve Steps to address those psychological kinds of “fear,” is wasting their time and the time of their protégées. The magnificent spiritual text, story and how-to book, “Alcoholics Anonymous" is a spiritual book presenting a spiritual process of recovery – not a science book. Human physiology, psychology certainly is affected by spiritual side of our humanity, but treating those elements first is huge mistake. The Realm of the Spirit is always primary.
We resent God for having failed us. It is hating God.
The only way lick fear is to wake up and disconnect from the source of thinking that feeds worry and doubt. We can do that on a continual, daily basis through an ardent Step Eleven lifestyle. By rising above thoughts through meditation, we develop mastery over all resentment, even the one flavored "FEAR".
