Leprosy was a common disease in the time of our Lord. On one occasion in the scripture Jesus healed a leper. It is Jesus who is able to bring about that cleansing to a man who was leprous. It is often seen spiritually as an analogy of sin and how we are corrupted by sin in our life. It is that touch of Jesus that cleanses us. The Lord renews us and make us healthy in our souls.
