John 8:44 ESV You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.
When we learn about the mentality and tactics of domestic abusers, sociopaths, narcissists and all that entire company of wicked ones, we see that in so many (and I suppose we could even say “all”) of their methods, lying is at the root of the thing. Deception. Slander. Reviling. Crazy-making. Accusing. All of it is based upon this one fundamental evil – lying.
You notice in the Scripture above why this is the case. The devil is not only a liar, he is the father of lies. He is the originator of lying. And he spawns lying offspring. If the devil’s mouth is open, he is lying. And so it is with his sons and daughters.
