What is Darkness and what makes it Evil;
Darkness is the absence of light, its the direct opposite of light. While light illuminates, darkness obfuscate. Darkness comes from a place of nothingness. In Gen 1:2 (And the earth was without form and void;and darkness was upon the face of the deep). Our God is a God of light.
Why Is there A Concept Of Darkness Being Evil?
According to the scriptures, darkness is a place of nothingness and absolute desolation. Prov 2:13 ( Who leave the path of uprightness, to walk in the ways of darkness). Darkness denotes a state of blindness and absolute complete and alter insignificancy. In Prov 4:19 ( The ways of the wicked is as darkness: they know not at what they stumble).
