There appears to be a dearth of literature concerning this area of doctrine. When writing of heaven, many tracts, sermons and systematic theology textbooks go into length concerning the blessedness of heaven. Heaven is devoid of any tears or sorrow.
The saints in heaven even have knowledge and awareness towards one another and this awareness is sometimes mentioned in some writer’s discourses on heaven. Details of “heavenly geography,” such as the “streets of gold” and the “pearly gates” are also mentioned, but the relationship that the saints have towards the wicked in hell is a neglected subject. Rarely is found the saints’ awareness of hell, much less their visual sight of the damned.
