"Then Jesus left the vicinity of Tyre and went through Sidon, down to the Sea of Galilee and into the region of the Decapolis. There some people brought to him a man who was deaf and could hardly talk, and they begged him to place his hand on the man." NIV translation
Now, we see the faith of some people in bringing a deaf man to Jesus. They believed that Jesus could physically heal him and so they brought him to the place for healing. We must ask ourselves whether we have that same kind of faith, today, as Christians.
"After he took him aside, away from the crowd, Jesus put his fingers into the man's ears. Then he spit and touched the man's tongue. He looked up to heaven and with a deep sigh said to him, 'Ephphatha!' (which means, 'Be opened!'). At this, the man's ears were opened, his tongue was loosened and he began to speak plainly." NIV translation
Jesus took the man away from the crowd to heal him and in this we see a big difference compared to the so-called faith healers of our day. It wasn't about putting on a show for a crowd but simply healing the man. We notice that Jesus touched the man physically and may wonder why He did so when He had not needed to touch the girl to drive out the demon. Sometimes, Jesus used aids to healing such as mud or a physical touch based on the circumstances and the amount of faith of the one being healed.
"Jesus commanded them not to tell anyone. But the more he did so, the more they kept talking about it. People were overwhelmed with amazement. 'He has done everything well,' they said. 'He even makes the deaf hear and the mute speak.'"NIV translation
Once again, we see Jesus tell the people not to tell people about this healing but they continued to speak of it. He wanted them to see the spiritual healing but all they were focused on was the physical.
It is much the same today as some people put on big "healing services" or "miracle services" and schedule them like some kind of circus act. They are usually fake and are not what Jesus did in His ministry.
