John 8:54-55

8:54 Jesus replied, “If I glorify myself, my glory is worthless. The one who glorifies me is my Father, about whom you people say, ‘He is our God.’ 8:55 Yet you do not know him, but I know him. If I were to say that I do not know him, I would be a liar like you. But I do know him, and I obey his teaching.
