Lies are falsehoods that are deliberately cast by their creators to hide the truth.  Lies are fictions designed to lead astray.  Lies are used to deceive and manipulate.  Those who create lies have shattered the relational matrix of reality, and are therefore accountable to God for their ontological disdane of his character.  Liars are idolaters.  They believe in false doctrine so they can walk in darkness and practice evil.  Liars have taught themselves to live independent of the Truth, and this is the beginning of lie-based thinking.
