Why Islam is truth not Christianity

To determine whether Islam or Christianity is true we must focus upon the divergence in beliefs held by the religions. Both Islam and Christianity believe in the same messiah. Both religions believe in the immaculate conception of Jesus of Nazareth, that he lived a perfect and sinless life, and that through him the covenant between God and Abraham was fulfilled as laid out in the Torah (Old Testament), the holy word of God [And mention] when the angels said, "O Mary, indeed Allah gives you good tidings of a word from Him, whose name will be the Messiah, Jesus, the son of Mary - distinguished in this world and the Hereafter and among those brought near [to Allah ]." Quran 3:45 "...for the Child who has been conceived in her is of the Holy Spirit. She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins." (bible) Matthew 1:21 The point of contention between the religions is not the role that Jesus played in the fulfillment religious texts, nor the miracles he performed, but in his divinity. While Muslims believe Jesus the Messiah was merely a prophet, Christianity claims that he was the physical avatar of God and was thus divine. To Christians, God is Triune - he exists in three states as needed but is always one creature. In the same way that mist, water, and ice are all still the same chemical but merely different states of matter, God can be Father, Son, and Holy Spirit while still being the same entity at its core. Each state merely emphasizes a different set of characteristics. Because of this, Christians worship and pray to Jesus/God while Muslims see this as blasphemous. Both religions hold to the Torah, the law of God as laid out in the Old Testament. In the Ten Commandment God forbade the worship of graven images - and to a Muslim who thinks Jesus son of Mary is a man, praying to him is sacrilegious. An interesting point can be made, however, in that the Quran implies that Jesus son of Mary was an extension of God, the same as Christians believe. Though Christ never directly said he was God (as was forbidden by Jewish law to which Jesus was held) his divinity is encapsulated in holy text shared by the Quran and Bible. The Quran routinely addresses Jesus as Kalimat Allah which translates as "a Word of God." This can be seen in the following verses of the Quran: 19:34, 4:171, 3:45, 9:40. This title, Word of God, is only ever used in the Quran in regard to Jesus son of Mary. Of all the prophets who spoke the truth of God, only Jesus is the Word of God (Kalimat Allah). The reason this is important is because as said earlier, both Islam and Christianity hold to the Torah, which is the Old Testament, and believe the work to be holy scripture. The first verse of the holy Torah is: Genesis 1:1 " In the beginning was the Word, and the Word was with God and the Word was God." The phrase "the Word was God" in Arabic is "w kan al'Kalimat Allah" which is the title reserved for Jesus son of Mary. And yet it is only the Christian faith which openly professes and practices that Jesus son of Mary was divine and should be recognized as an extension of God (Allah), the Creator. Most Muslims say that Jesus was not divine, but the Quran says otherwise.
