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>.
John 17:3 And this is life eternal, that they might know thee the only true God, even Yahshua the Messiah who is sent forth
Yahshua is God manifest in the flesh (1 Tim 3:16, Col 1:15). Yahshua 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.
Luke 2:11 For unto you is born this day in the city of David a Savior, who is the Messiah our God
Isaiah 43:11, and Luke 2:11, confirm that Yahshua is the manifestation of Yahweh in the flesh. He is the image of God, not a separate person of the Christian trinity fable.
