"I had this glory," He says, "because You loved Me." For "You loved Me" is placed in the middle. As He said above (John 17:5), "Glorify Me with the glory which I had before the world existed," so now He says that the glory of the Godhead was given to Him before the foundation of the world. For truly the Father gave Him the Godhead, as a Father to a Son, by nature. Since He begat Him, then as the Author of His being, He is necessarily also called the Author and Bestower of glory.
Jn. 17:25. Righteous Father! The world has not known You; but I have known You, and these have known that You sent Me.
After such a prayer for the believers and the promise to them of so many blessings, He finally utters something merciful and worthy of His love for mankind. He says: "Righteous Father! I would wish that all people also receive such blessings as I have asked for the faithful, but they have not known Thee and therefore will not receive that glory and those rewards."
"And I have known You." He hints here also at the Jews, who said that they know God, and shows that they do not know the Father. For by "the world" in many places he means the Jews.
Jn. 17:26. And I have made known to them Thy name, and will make it known, that the love with which Thou hast loved Me may be in them, and I in them.
Although the Jews say that You did not send Me, yet to these disciples of Mine "I have made known Your name and will make it known." How will I make it known? By sending down upon them the Spirit, Who will guide them into all truth. And when they come to know Who You are, then the love with which You loved Me will be in them, and I in them. For they will know that I am not estranged from You, but am greatly beloved, that I am Your true Son and am united with You. And having learned this, they will keep faith in Me and love, and finally, I will abide in them because they are such that they have known You and honor Me as God. And they will keep their faith in Me unshaken.
