A person who is sick will always want to take several medicines. Certain birds will always be wanting to look at cool moonshine. Good people will always want to help the bad people and to see that the badness in them is removed and they are cleansed. It is only one who has a disease and is sick that wants a doctor. A healthy man does not want a doctor. Similarly, people who are suffering from the disease of disbelief can be cured by good people.
