The undoing of fear is an essential part of the Atonement value of miracles. A miracle is a universal blessing from God through me to all my brothers. It is the privilege of the forgiven to forgive. Miracles are a way of earning release from fear. Revelation induces a state in which fear has already been abolished.
Miracles are thus a means and revelation is an end.
Miracles praise God through you. They praise Him by honoring His creations, affirming their perfection. By recognizing spirit, miracles adjust the levels of perception and show them in propr alignment. This places spirit at the center, where it can communicate directly. Miracles should inspire gratitude, not awe.
