Jesus prayed:

11b "Holy Father, keep them through your name which you have given me, that they may be one, even as we are. 12 While I was with them in the world, I kept them in your name. Those whom you have given me I have kept. None of them is lost, except the son of destruction, that the Scripture might be fulfilled. 13 But now I come to you, and I say these things in the world, that they may have my joy made full in themselves. 14 I have given them your word. The world hated them, because they are not of the world, even as I am not of the world. 15 I pray not that you would take them from the world, but that you would keep them from the evil one. 16 They are not of the world even as I am not of the world. 17 Sanctify them in your truth. Your word is truth. 18 As you sent me into the world, even so I have sent them into the world. 19 For their sakes I sanctify myself, that they themselves also may be sanctified in truth."

John 17:11b-19 - World English Bible

Those who spoke in the name of a king make pronouncements as if the king himself were present and enforced his decrees with the might of his army. Speaking in the name of any regent implied the presence and power of such a royal person. When Jesus prayed through the name the Father gave him, he implied the same. Replace the word "name" with the phrase "presence and power" in 17:11b-12 to get a taste of his real meaning.

Jesus employed the "name" of the Father as a means to an end: intimate union with his followers. The "name" (i.e., presence and power) kept his followers safe from the Evil One (except Judas) and filled them with joy. His followers held fast to the "word" of the Father (his command to believe in his Son) and those in the common culture hated Christians for their devotion to the Lord, their beliefs and their lifestyle of charity. Indeed, the evangelist saw that hatred divide the world in two, dark vs. light, evil vs. good, pagan vs. Christian. Yet, the Lord sent his disciples out into the other world to convert it, armed only with the "truth." In this sense, God's truth was not only a message in the form of propositions found in the creed or syllogisms one used in apologetics, but much deeper, a knowledge that flowed from intimate union with the divine, a relationship that made one right with the Father. ("Your word is truth" was a reference to Psalm 119:142.)
