Quote from ACIM Text Chapter 7, Section 9 - The Extension of the Kingdom.

Be confident that you have never lost your Identity and the extensions which maintain It in wholeness and peace. Miracles are an expression of this confidence. They are reflections of both your proper identification with your brothers, and of your awareness that your identification is maintained by extension. The miracle is a lesson in total perception. By including any part of totality in the lesson, you have included the whole.
