Jesus said: “When he (Lucifer) lies, he speaks of himself , for he is a liar and the father of lies.” John 8:44

In other words, when the Devil opens his mouth, he is lying.  He is incapable of telling the truth.

Please notice I use the following interchangeably: Satan, Lucifer, Devil, father of lies, liar, etc.  

His biggest lie is he does not exist and is a figment of your imagination.

He is very dangerous to those that believe he does not exist.

Lucifer hates the truth. He hates Jesus Christ and all human beings.

His deception, destruction and divisiveness are endless.

Nobody lies better than Satan.

He is the Father of lies.

They all refer to the same.
