Notice how Jesus instructs some of the recipients of miraculous healing-
Mark 1:40-45 And a leper came to him, imploring him, and kneeling said to him, “If you will, you can make me clean.” Moved with pity, he stretched out his hand and touched him and said to him, “I will; be clean.” And immediately the leprosy left him, and he was made clean. And Jesus sternly charged him and sent him away at once, and said to him, “See that you say nothing to anyone, but go, show yourself to the priest and offer for your cleansing what Moses commanded, for a proof to them.” But he went out and began to talk freely about it, and to spread the news, so that Jesus could no longer openly enter a town, but was out in desolate places, and people were coming to him from every quarter.
Mark 5:39-43 And when he had entered, he said to them, “Why are you making a commotion and weeping? The child is not dead but sleeping.” And they laughed at him. But he put them all outside and took the child's father and mother and those who were with him and went in where the child was. Taking her by the hand he said to her, “Talitha cumi,” which means, “Little girl, I say to you, arise.” And immediately the girl got up and began walking (for she was twelve years of age), and they were immediately overcome with amazement. And he strictly charged them that no one should know this, and told them to give her something to eat.
Mark 7:33-36 And taking him aside from the crowd privately, he put his fingers into his ears, and after spitting touched his tongue. And looking up to heaven, he sighed and said to him, “Ephphatha,” that is, “Be opened.” And his ears were opened, his tongue was released, and he spoke plainly. And Jesus charged them to tell no one. But the more he charged them, the more zealously they proclaimed it.
I am struck by something. In certain situations Jesus instructs people to tell no one about His miraculous works, yet they told everyone. He tells us to tell everyone, yet all too often, we tell no one.
