Listen to the words Jesus speaks of His relationship to the Father and see how consistently He uses the words not and nothing of himself.
"The Son can do nothing by himself" (John 5:19)
"By myself I can do nothing; I judge only as I hear, and my judgement is just, for I seek not to please myself but him who sent me" (John 5:30)
"I do not accept praise from men" (John 5:41)
"For I have come down from heaven not to do my will" (John 6:38)
"My teaching is not my own" (John 7:16)
"I am not here on my own" (John 7:28)
"I have not come on my own; but he sent me" (John 8:42)
"I am not seeking glory for myself" (John 8:50)
"The words I say to you are not just my own" (John 14:10)
These words of testimony, spoken by the Lord himself, reveal the deepest motivation of His life and work. They show how the Father was able to work His redemption through the Son. They show the state of heart that became Him as the Son of the Father. They teach us the essential nature and life of the redemption that Christ accomplished and now communicates to us. It is this: He was nothing that God might be all. He resigned himself to the Father's will and power that He might work through Him. Of His own power, His own will, His own glory, His whole mission with its works and teaching-of all this, He said, I am nothing. I have given myself to the Father to work; He is all.
This life of absolute submission and dependence upon the Father's will, Christ found to be the source of perfect peace and joy. He lost nothing by giving all to God. His humility was simply the surrender of himself to God, to allow Him to do in Him what He pleased, regardless of what men might say of Him or do to Him. This is the true self-denial to which our Savior calls us, the acknowledgement that self has nothing good in it, except as an empty vessel for God to fill.
