John 8:44 Ye are of [your] father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Jesus Christ just told you who their father is, do you believe Him. A murderer from the beginning, who was the first murderer? CAIN. Cain's father was the Devil and these fakes are Cain's offspring. Lets end with 1John.
1John 3:12 Not as Cain, [who] was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.
Do you believe Jesus Christ or man? Jesus Christ Words are good enough for me.
