“There are four types of judges:1- There are those who unknowingly judge right. They will go to Hell.2- There are those who unknowingly judge wrong. They will also go to Hell.3- There are those who knowingly judge wrong. They will also go to Hell.4- There are those who knowingly judge right. They will go to Paradise.”
