The purpose of time is to enable you to learn how to use time constructively. It is thus a teaching device and a means to an end. Time will cease when it is no longer userful in facilitating learning. Miracles are teaching devices for demonstrating it is as blessed to give as to receive. They simultaneously increase the strength of the giver and supply strength to the receiver.
Miracles transcend the body.
They are sudden shifts into invisibility, away from the bodily level. That is why they heal. A miracle is a service. It is the maximal service you can render to another. It is a way of loving your neighbor as yourself.
