Is there a method to follow for healing? There is usually a point of contact through which God's power flows. A woman in a large crowd thought "'If I just touch his clothes, I will be healed'" (Mk 5:28). Then "she felt in her body that she was freed from her suffering" (:29). "She [had] heard about Jesus" (:27) and approached him from behind in the crowd. Others had heard also. "When the men of that place recognized Jesus . . . [people] begged him to let the sick just touch the edge of his cloak, and all who touched him were healed" (Mt 14:35,36). Also Paul's "handkerchiefs and aprons that had touched him were taken to the sick, and their illnesses were cured" (Ac 19:12). Did God impregnate the cloth with supernatural energy? That would be science fiction. God is omnipresent. In his omnipotence he knows when to personally manifest his power. "'I am watching to see that my word is fulfilled'" (Jer 1:12).
Another point of contact is touch. "Jesus put forth his hand and touched him . . . and immediately his leprosy was cleansed" (Mt 8:2,3). "He touched her hand and the fever left her" (Mt 8:14). He "put fingers into his ears . . . and touched his tongue" (Mk 7:33) and his "ears were opened . . . and he spoke plainly" (:35). "They brought a blind man unto him, and besought him to touch him" (Mk 8:22).
