Matt 3
9: and do not presume to say to yourselves, `We have Abraham as our father'; for I tell you, God is able from these stones to raise up children to Abraham.

John 8
37: I know that you are descendants of Abraham; yet you seek to kill me, because my word finds no place in you.
38: I speak of what I have seen with my Father, and you do what you have heard from your father."
39: They answered him, "Abraham is our father." Jesus said to them, "If you were Abraham's children, you would do what Abraham did,
40: but now you seek to kill me, a man who has told you the truth which I heard from God; this is not what Abraham did.
41: You do what your father did." They said to him, "We were not born of fornication; we have one Father, even God."
42: Jesus said to them, "If God were your Father, you would love me, for I proceeded and came forth from God; I came not of my own accord, but he sent me.
43: Why do you not understand what I say? It is because you cannot bear to hear my word.
44: 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 has nothing to do with the truth, because there is no truth in him. When he lies, he speaks according to his own nature, for he is a liar and the father of lies.
