Jesus took him aside from the multitude with perhaps his immediate family – the multitude would not see this miracle taking place. Why not? Because Christ did not heal to play to the crowds; he did not come into the world to create a spectacle to simply impress people.
The healing is to be private, individual. Conversion is not a public event but a very personal event. It is something within us, in the privacy of our hearts. Sometimes, we ourselves can scarcely follow the change that the Spirit of God is working in us. Christ’s work here is a picture which illustrates an aspect of conversion, repentance, which is a private act. We come to God on our own for salvation of our soul.
Christ spat on his finger and touched the man’s tongue, the part that needed to be healed. Christ saves souls by imparting something from himself and touching our dead souls. We must be spiritually united with him if we are to be saved. Principally he imparts forgiveness. This he did, as was prophesied thousands of years before, by giving his life on the cross of Calvary, and taking on himself all the guilt and punishment of the sins of all his people. He earned the right to impart forgiveness and new life to us. He also gives us righteousness. We cannot get into heaven; we do not have the right to enter into the presence of a holy God. But Christ lived a perfect life of righteousness in this world, and from his store of righteousness he has the ability to impart this to us, qualifying us to stand before God. He came to be our substitute, our sin bearer. Do we wish to be changed? He must give himself to us to impart new life, so that we are made spiritual people.
