"The people who walked in darkness have seen a great light; those who dwelt in the land of the shadow of death, on them a light has shined."
Isaiah 9:2
"Why is my language not clear to you? Because you are unable to hear what I say. You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies."
John 8:43-44
