i believe you should accually read the Bible before you talk about it.
It is an article of faith for every Muslim to believe in all the Prophets of God (Allah in Arabic) and all revelations of God (Allah). However, the present day Bible has the first five books of the Old Testament attributed to Moses (peace be upon him) and the Psalms attributed to David (peace be upon him). Moreover the New Testament or the four Gospels of the New Testament are not the Taurah, the Zaboor or the Injeel, which the Qur'an refers to. These books of the present day Bible may partly contain the word of God but these books are certainly not the exact, accurate and complete revelations given to the prophets.
But why those previous revelations were not completely preserved?
Prophet Jesus (peace be upon him) was
not sent to the whole world, but only to the children of Israel.
In fact, God says in the Holy Qur'an 3:49
"And (appoint him) an apostle to the Children of Israel"
I'll also quote from your own Bible:
Matthew 15:24
"I was sent only to the lost sheep of the house of Israel"
Matthew 10:5-6
"Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel."
Acts 11:19
"Now they which were scattered abroad upon the persecution that arose about Stephen travelled as far as Phenice, and Cyprus, and Antioch, preaching the word to none but unto the Jews only."
On the other hand Prophet Muhammad (peace and blessings be upon him) was sent to the whole worlds:
"We sent thee not, but as a Mercy for all creatures" Holy Qur'an 21:107
So God almighty promises to save his word which is meant for the whole of humanity (that is the Holy Qur'an).
