Read: Leviticus 14
The priest is to go outside the camp and examine them. If they have been healed of their defiling skin disease, the priest shall order that two live clean birds and some cedar wood, scarlet yarn and hyssop be brought for the person to be cleansed. Lev 14:3-4
In Chapter 14 we move into a further development of this whole matter of handling leprosy. Here we have the cleansing of the leper. Notice that the leper does not go through all the ritual which follows in order to be healed; he does it in order to be cleansed. He is already healed. Healing is something only God can do. It is the sovereign act of God and it takes place in the inner life of a believer. His cleansing of a person allows the one who is healed to understand God’s basis and purpose for the healing. God wants the inner cleansing to be reflected in the outward life and actions of the person who is healed. That is the picture which is drawn here.
You and I can’t heal our leprous hearts. If there is some wrongful attitude within us, if we burn with envy or jealousy or resentment toward one another, if we are impatient and upset and angry at heart — we seldom see these things in ourselves until God puts us into circumstances where they are brought out — and then the only thing we can do is take them to him because we are helpless victims caught up in these dangerous attitudes. When you finally see yourself like that, then you can say, Lord, heal me! And God does! With a touch of his grace he changes our attitude. We stop being defensive about it and we admit it. And then the leprosy is arrested, its action is stopped, and we are healed.
