The opposite of love is fear.

The first corrective step in undoing the error is to know first that the conflict is an expression of fear. Say to yourself that you must somehow have chosen not to love, or the fear could not have arisen. Then the whole process of correction becomes nothing more than a series of pragmatic steps in the larger process of accepting the Atonement as the remedy. These steps may be summarized in this way: 

• Know first that this is fear.

•  Fear arises from lack of love. 

• The only remedy for lack of love is perfect love.

•  Perfect love is the Atonement.

A Course in Miracles . Foundation for Inner Peace. Kindle Edition. 

The Course makes clear that the basic problem which humans have is fear. Fears arise in a myriad of forms and are based on the false belief that we are a body, forgetting that we are primarily a soul. As a soul born from Unconditional Love where  there is no fear. Fear in the realm of Spirit is nonexistent. So when we are afraid we have forgotten that we are loved unconditionally.

In Alcoholics Anonymous it is suggested, in step eleven, that we improve our conscious contact with God through prayer and mediation. This prayer and meditation diminishes, if not eliminates, our fears as we remember who and what we really are.

In Unitarian Universalism we covenant together to affirm and promote the inherent worth and dignity of every person. This inherent worth and dignity arises from the unconditional love of our creator as the Universalist theology teaches us.

Today, we remember and reflect on who and what we really are, the product of unconditional love of our Transcendent Source. In this realm fear is nonexistent and has no meaning for the opposite of fear is unconditional love.
