They bring more love both to the giver AND the receiver. The use of miracles as spectacles to induce belief is a mis- understanding of their purpose. Prayer is the medium of miracles. It is a means of communication of the created with the Creator. Through prayer love is received, and through miracles loves is expressed.
Miracles are thoughts.
Thoughts can represent the lower or bodily level of experience, or the higher or spiritual level of experience. One makes the physical, and the other creates the spiritual. Miracles ar both beginnings and endings, and so they alter the temporal order. They are always affirmations of rebirth, which seem to go back but really go forward. They undo the past in the present, and thus release the future.
