John 8:29

(Tr xl. 6) And though both are together, yet one is sent, the other sends. For the mission is the incarnation; and the incarnation is of the Son only, not of the Father. He says then, He that sent Me, meaning, By whose Fatherly authority I am made incarnate. The Father however, though He sent the Son, did not withdraw from Him, as He proceeds to say: The Father hath not left Me alone. For it could not be that where He sent the Son, there the Father was not; He who says, I fill heaven and earth. (Jer. 33) And He adds the reason why He did not leave Him: For I do always those things that please Him; always, i. e. not from any particular beginning, but without beginning and without end. For the generation from the Father hath no beginning in time.

I do not issue orders to you, as if I were some great person. For though I am bound for His name, I am not yet perfect in Jesus Christ. For now I begin to be a disciple, and I speak to you as my fellow-servants. For it was needful for me to have been admonished by you in faith, exhortation, patience, and long-suffering. But inasmuch as love suffers me not to be silent in regard to you, I have therefore taken upon me first to exhort you that ye would run together in accordance with the will of God. For even Jesus Christ does all things according to the will of the Father, as He Himself declares in a certain place, "I do always those things that please Him." Wherefore it behoves us also to live according to the will of God in Christ, and to imitate Him as Paul did. For, says he, "Be ye followers of me, even as I also am of Christ."

"And the Father is with Me." That they may not deem the "who sent Me" to be a mark of inferiority, He saith, "is with Me"; the first belongeth to the Dispensation, the second to the Godhead. "And He hath not left Me alone," for I do always those things that please Him. Again He hath brought down His discourse to a humbler strain, continually setting Himself against that which they asserted, that He was not of God, and that He kept not the Sabbath. To this He replieth, "I do always those things that are pleasing unto Him"; showing that it was pleasing unto Him even that the Sabbath should be broken. So, for instance, just before the Crucifixion He said, "Think ye that I cannot call upon My Father?" And yet by merely saying, "Whom seek ye?" He cast them down backwards. Why then saith He not, "Think ye that I cannot destroy you," when He had proved this by deed? He condescendeth to their infirmity. For He took great pains to show that He did nothing contrary to the Father. Thus He speaketh rather after the manner of a man; and as "He hath not left Me alone," was spoken, so also was the, "I do always those things that are pleasing unto Him."
