John 8:54-56

Jesus answered, If I glorify myself, my glory is nothing: it is my Father that glorifieth me; of whom ye say, that he is your God; and ye have not known him: but I know him; and if I should say, I know him not, I shall be like unto you, a liar: but I know him, and keep his word. Your father Abraham rejoiced to see my day; and he saw it, and was glad.
