Healing is no guarantee that the same disease will not be repeated later. Even in medical cure this possibility remains. The healing that takes place in retreat centres is mostly faith-healings. They occur due to our faith in God's healing power and are intended to foster our faith in Jesus' saving power. They are more symbols or manifestations of Jesus' salvific act in us. If we co-operate with Jesus' salvific work in us and shun the path of sin and foster our faith in Jesus Christ our Saviour, our physical and spiritual health will only improve. "Sin no more so that nothing worse may happen," said Jesus to one who was healed.
Man has the freedom either to co-operate with the salvific work of Jesus in him or to reject it and live according to his sensual appetites. When he freely chooses the latter, he becomes a worse sinner. He becomes the abode of seven evil spirits' instead of the one which was cast out during the retreat. Hence those who were renewed are to be vigilant against their own fragile human nature and temptations of the world. They have to be in constant touch with God, the Power House of our spiritual energy and foster the spiritual life by listening to the word of God and receiving sacraments. In case we fail, admitting our own weakness, we have to get reconciled with God and our brethren.
