Again he left the district of Tyre and went by way of Sidon to the Sea of Galilee, into the district of the Decapolis. And people brought to him a deaf man who had a speech impediment and begged him to lay his hand on him. He took him off by himself away from the crowd. He put his finger into the man’s ears and, spitting, touched his tongue; then he looked up to heaven and groaned, and said to him, “Ephphatha!” (that is, “Be opened!”) And (immediately) the man’s ears were opened, his speech impediment was removed, and he spoke plainly. He ordered them not to tell anyone. But the more he ordered them not to, the more they proclaimed it. They were exceedingly astonished and they said, “He has done all things well. He makes the deaf hear and (the) mute speak.” (Mk 7:31-37)
The Evangelist presents the movements of Jesus. We are not sure of the intentions of Mark for the geographical presentation of the movements of Jesus does not seem to be accurate. Jesus is already in the north of Galilee and he moves still further north to come to the east of Galilee. Again he goes into the territory of Non Jewish region.
He meets a man who had speech impediment and deaf. Here faith, of the person healed or the people who brought the man to Jesus, is not demanded. Jesus performs this miracle without the people expressing their faith. So the miracle is worked purely from the side of Jesus except for the request from the people.
Jesus performs miracles on his own. It could be to reveal the glory of God to the people who do not have faith in God. God’s glory is revealed independent of the peoples faith. But people recognized his works and appreciated his activities. People of non Jewish faith see in Jesus a good man who went about doing good. He has done all things well.
