John 17:6-8

17:6-8 "I have shown forth your name to the men whom you gave me out of the world. They were yours and you gave them to me, and they have kept your word. Now they realize that everything you gave me comes from you, because I gave to them the words you gave to me, and they received them, and they truly know that I came forth from you, and they believe that you sent me."

Jesus gives us a definition of the work that he did. He says to God: "I have shown forth your name."

There are two great ideas here, both of which would be quite clear to those who heard this saying for the first time.

(i) There is an idea which is an essential and characteristic idea of the Old Testament. In the Old Testament name is used in a very special way. It does not mean simply the name by which a person is called; it means the whole character of the person in so far as it can be known. The Psalmist says: "Those who know thy name put their trust in thee" ( Psalms 9:10 ). Clearly that does not mean that those who know what God is called will trust him; it means that those who know what God is like, those who know his character and nature will be glad to put their trust in him.

The psalmist says: "Some boast of chariots, and some of horses; but we boast of the name of the Lord our God" ( Psalms 20:7 ). This means that he can trust God because he knows what he is like. The Psalmist says: "I will ten of thy name to my brethren" ( Psalms 22:22 ). This was a psalm which the Jews believed to be a prophecy of the Messiah and of the work that he would do; and it means that the Messiah's work would be to declare to his fellow-men what God is like. It is the vision of Isaiah that in the new age, "My people shall know my name" ( Isaiah 52:6 ). That is to say that in the golden days men will know fully and truly what God is like.

So when Jesus says: "I have shown forth your name," he is saying: "I have enabled men to see what the real nature of God is like." It is in fact another way of saying: "He who has seen me has seen the Father" ( John 14:9 ). It is Jesus' supreme claim that in him men see the mind, the character, the heart of God.

(ii) But there is another idea here. In later times when the Jews spoke of the name of God they meant the sacred four-letter symbol, the tetragrammaton as it is called, IHWH. That name was held to be so sacred that it was never pronounced, except by the High Priest when he went into the Holy of Holies on the Day of Atonement.

These four letters stand for the name Yahweh ( Hebrew #3068 and Hebrew #3069 ). We usually speak about Jehovah and the change in the vowels is due to the fact that the vowels of Jehovah are those of Adonai ( Hebrew #136 ), which means "Lord." In the Hebrew alphabet there were no vowels at all. Later the vowel sounds were shown by little signs put above and below the consonants. The four letters Y-H-W-H were so sacred that the vowels of 'Adonai were put below them, so that when the reader came to IHWH he would read, not Yahweh, but 'Adonai. That is to say, in the time of Jesus the name of God was so sacred that ordinary people were not even supposed to know it, far less to speak it. God was the remote, invisible king, whose name was not for ordinary men to speak. So Jesus is saying: "I have told you God's name; that name which is so sacred can be spoken now because of what I have done. I have brought the remote, invisible God so close that even the simplest people can speak to him and take his name upon their lips."

It is Jesus' great claim that he showed to men the true nature and the true character of God; and that he brought him so close that the humblest Christian can take his unutterable name upon his lips.
