John 8:43-47

Why do ye not understand my speech? Even because ye cannot hear my word. Ye are of your father the devil, and the lusts of your father it is your will to do. He was a murderer from the beginning, and standeth 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 thereof. But because I say the truth, ye believe me not. Which of you convicteth me of sin? If I say truth, why do ye not believe me? He that is of God heareth the words of God: for this cause ye hear them not, because ye are not of God.
