As there are precise physical laws, so there are precise spiritual laws, too. To obtain any given result an intelligence is needed to carry out the plan. We cannot expect God to break these laws to give any one a day longer in life. Every healing must be a planned effort, it is not automatic. This provides the prima facie evidence of the co-operation of those, in Spirit, who are agents for the carrying out of the divine plan.
Healing can only take place within the framework of the physical and spiritual laws.
Therefore a healing is the result of the intelligent application of remedial forces within these laws. This premise is, of course, based on the acceptance of a spirit realm, in which we all shall take our place in the time to come. This postulate was accepted by an Archbishops' Commission but the Report was officially suppressed by the bishops and there is an incontrovertible mass of evidence to prove the truth of human survival in another way of life. This recognition of the existence of individual spirits in another life, equally opens the door to admit the existence of good spirit intelligences who are part of the divine ministry. You would supplement your physical knowledge by acquiring wisdom of the spiritual forces that you could direct to heal the sick.
