Good can withstand any form of evil.

The resurrection demonstrated that nothing can destroy truth. Good can withstand any form of evil, as light abolishes forms of darkness. The Atonement is therefore the perfect lesson. It is the final demonstration that all the other lessons I taught are true. If you can accept this one generalization now, there will be no need to learn from many smaller lessons. You are release from all errors if you believe this. T-3.1.7:6-11 

A Course In Miracles

The Atonement, in A Course Of Miracles, is the undoing of the separation. It is becoming aware of the Oneness that in truth we have never left. They killed Jesus' body when they crucified Him but they couldn’t kill His spirit which was resurrected and lives on. It is the light of the resurrection which dissolves darkness. If we experience the light of the Atonement we need to learn and know nothing else.

In Alcoholics Anonymous it is suggested, in step eleven, that we improve our conscious contact with God. This suggestion encourages us to accept the Atonement.

In Unitarian Universalism we covenant together to affirm and promote the inherent worth and dignity of every person which is a recognition of the Atonement. The Atonement in the context of this principle means the Oneness of God’s creation which is imbued with worth and dignity.

Today, it is suggested that we rise above the divisiveness, exclusion, and separation of the world of the ego and enter into the realm of Oneness which is the unconditional love of God if even for a few seconds, or minutes or even longer if we wish.
