So Jesus said, "When you have lifted up the Son of man, then you will know that I am he, and I do nothing on my own authority but speak thus as the Father taught me. And he who sent me is with me; he has not left me alone, for I always do what is pleasing to Him." ( John 8:28-29)

"For I have not spoken on my own authority; the Father who sent me has himself given me commandment what to say and what to speak. And I know that his commandment is eternal life. What I say, therefore, I say as the Father has bidden me." ( John 12:49-50)
