Jesus Christ whom thou hast sent
John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent
John 17:3 And <G1161> this <G3778> is <G2076> life <G2222> eternal <G166>, that <G2443> they might know <G1097> thee <G4571> the only <G3441> true <G228> God <G2316>, and <G2532> Jesus <G2424> Christ <G5547>, whom <G3739> thou hast sent <G649>.
And this is life eternal, that they might know thee the only true Yahweh, even Yahshua (the Savior) the Messiah who is sent forth (John 17:3).
Yahshua (the Savior) is Yahweh manifest in the flesh (1 Tim 3:16, Col 1:15). He did not come forth from Himself, but He proceeded or came forth from Yahweh. The same can be said of his true name (John 5:43).
Isaiah 43:11 I, even I, am Yahweh; and beside me there is no Savior
To understand the identity of Yahshua in the Old Testament, we need to comprehend the meaning of His true name. The name of our God is not Jesus, it is Yahshua (the Savior).
For unto you is born this day in the city of David a Savior, who is the Messiah of Yahweh (Luke 2:11).
Isaiah 43:11, and Luke 2:11, confirm that Yahshua (whose name means Savior) is the manifestation of Yahweh in the flesh. He is the image of God, not a separate person of the Christian trinity fable.
