John 8:51-55

51Verily, verily, I say to you, If a man shall keep my saying, he shall never see death. 52Then said the Jews to him, Now we know that thou hast a demon. Abraham is dead, and the prophets; and thou sayest, If a man shall keep my saying, he shall never taste of death. 53Art thou greater than our father Abraham, who is dead? and the prophets are dead: whom makest thou thyself? 54Jesus answered, If I honour myself, my honour is nothing: it is my Father that honoureth me; of whom ye say, that he is your God: 55Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like you: but I know him, and keep his saying.
