I want to obey Fathers words. And as Jesus told, he spoke what the Father had commanded him to speak, which is why his words are also Fathers words.
For I spoke not from myself, but the Father who sent me, he gave me a commandment, what I should say, and what I should speak. I know that his commandment is eternal life. The things therefore which I speak, even as the Father has said to me, so I speak.
John 12:49-50
Jesus therefore answered them, "My teaching is not mine, but his who sent me. If anyone desires to do his will, he will know about the teaching, whether it is from God, or if I am speaking from myself.
John 7:16-17
Jesus answered him, "If a man loves me, he will keep my word. My Father will love him, and we will come to him, and make our home with him. He who doesn't love me doesn't keep my words. The word which you hear isn't mine, but the Father's who sent me.
John 14:23-24
For he whom God has sent speaks the words of God; for God gives the Spirit without measure.
John 3:34
