Underlying order
This is not written in stone. When we see what appears to be a miracle, or a great healing, is it? I don't think that God breaks any rules. In the physical world he uses physics. In the spiritual world he uses metaphysics, or spiritual physics. When the two are crossed it is beyond our comprehension, but laws are still obeyed. Perhaps some laws appear to be suspended, but beneath there still must be an underlying order.
