Miracles are natural signs of forgiveness. Through miracles you accept God's forgiveness by extending it to others. Miracles are associated with fear only because of the belief that darkness can hide. You believe that what your physical eyes cannot see does not exist. This leads to a denial of spiritual sight.
Miracles rearrange perception and place all levels in true perspective.
This is healing because sickness comes from confusing the levels. Miracles enable you to heal the sick and raise the dead because you made sickness and death yourself, and can therefore abolish both. YOU are a miracle, capable of creating in the likeness of your Creator. Everything else is your own nightmare, and does not exist. Only the creations of light are real.
