Jesus says to them, My food is that I should do the will of him that has sent me, and that I should finish his work.
Jesus therefore answered and said to them, Verily, verily, I say to you, The Son can do nothing of himself save whatever he sees the Father doing: for whatever things he does, these things also the Son does in like manner. John 5:19
I am able to do nothing of Myself. As I hear, I judge; and My judgment is just, because I do not seek My will, but the will of the One having sent Me. John 5:30
because I have come down out of the heaven, not that I may do my will, but the will of Him who sent me. John 6:38
So Jesus told them, "My message is not my own; it comes from God who sent me..." John 7:16
He that loves me not does not keep my words; and the word which ye hear is not mine, but [that] of the Father who has sent me. John 14:24
"... But that the world may know that I love my Father, and just as my Father has taught me, so I have done. Rise up, let us depart from here.” John 14:31
