Jews no believe in Jesus being God's son, etc..

The belief that Jesus is God, part of the Trinity, the Messiah, or a prophet of God are incompatible with traditional Jewish views. Judaism has no special or particular view of Jesus, and very few texts in Judaism directly refer to or take note of Jesus. One of the most important Jewish principles of faith is the belief in one God and one God only with no partnership of any kind. http://en.wikipedia.org/wiki/Judaism's_view_of_Jesus

Jews are still waiting on their Messiah.

judaesim does not leave room in the Godhead for a compound unity. Usually messianic Jews will state that they do not believe in a trinity either, however, there are some messianic groups who do believe in the trinity(but they are rare when compaired to the rest of judaeism).

"There are none beside Me" was told to the jews directly from The word. It hasnt changed. Jesus of the New is Jehova of The Old.

Jesus isnt the Messiah. the bible says they are blinded to the truth. and when a jew becomes a christian they are so happy to know the truth.

Because it is hard to believe in a trinity when one of the sides is missing. Jesus was not the son of God according to the Jewish belief structure.

The early church (Jewish mainly) only believed in one God (Deuteronomy 6:4: The Lord our God is one.) and baptized into one name only. (Acts 2:38: Repent, and be baptized everyone of you into the name of Jesus, for the remission or forgiveness of sins.) That should solve the issue, but many regard the teachings of the early Catholics to be equally important. Many people from the age of the Apostles until catholic persecution, practiced Jesus name baptism and were the majority and the Catholics the minority; until the Justinian code (6th century) which allowed them to confiscate other churches (Who preached the one God and Jesus name baptism message.) properties. So, in light of that, let us look at some of these voices. The Post-Apostolic Fathers [Clement of Rome, Ignatius, Polycarp, Papias, and the document called The Shepherd of Hermas] - The post-apostolic fathers were committed to both monotheism and the deity of Christ, but made no effort at reconciling the two. As J. N. D. Kelly notes, the post-apostolic fathers appear "as witnesses to the traditional faith rather than interpreters striving to understand it" (Early Christian Doctrines [New York: Harper & Row, 1960], 90). Generally speaking, these men repeated the biblical assertions concerning both Father and Son but declined to speculate or theorize on the relation of the two in the Godhead. For them, monotheism was viewed as “the dividing line between the Church and paganism”. These Pre-Nicene Catholic fathers did not alter the teachings of the Apostles.

The Jewish Nation had a special relationship with God. Out of all the nations, tribes and tongues on the earth at that time God picked only them as his special possession. They were taught by the first Prophets and in their belief system they were taught that God was only one Being. A Being whom existed in raltion to them as only one Person. The Person of the Father. Due to their special relationship with him they also had been informed and carried with them this Beings name. They used it and we see it in Psalms 83:18 of the King James Version of the Bible. Deuteronomy 6:4 points out not that "God is One" but actually that YHWH our God is "One YHWH." Thus, there was no 3 YHWH's that made up some mysterious one God. There God was YHWH (Jehovah,Yahweh) the Father Only. There are many other factors which due to lack of time I'm unable to list. I do, However hope this aids you. Fact: The Trinity Doctrine or thought did not exist during the time of the Ancient Jewish people. It came about much later...roughly from 321 through to 381 a.d.
