This is the closest to a definition of Hell that i have (so far) come across in the writings of Herman Dooyeweerd :
. . . sin in its fullness does not mean the cutting through of the relation of dependence between the Creator and depraved creation, but that the fullness of being of Divine justice will express itself in reprobate creation in a tremendous way, and that in this process depraved reality cannot but reveal its creaturely mode of being as meaning.It will be meaning in the absolute subjective apostasy under the curse of God's wrath, but in this very condition it will not be a meaningless reality.
