We believe that Christianity is the total fulfillment of what the Jewish religion is all about. From the very beginning of time, God has placed His hand on those He chose to bless - from Seth in Genesis through the Abraham and the children of Israel. The religion that God gave to these ones (Judaism) looked forward to someone called the Messiah who would deliver the Jewish people from the dilemma of oppression and mistreatment. The sacrifices of the temple typified what would ultimately be provided by God Himself - the atonement for sin. This Savior was depicted in detail in Isaiah 53 as the One who would suffer for our sins.
In fact, this was all fulfilled in the Person of Jesus Christ who we understand to be the Son of God prophesied in the Old Testament - all the way back in the Torah - Genesis 3:15. The seed of the woman who would defeat the works of Satan is Jesus Christ. He suffered and died in exactly the same way that Isaiah 53 described. In dying for our sin, He is the Lamb of God who fulfilled what was anticipated by all the sacrifices that were offered annually on Yom Kippur.
I would encourage you to read the Scriptures (your Bible is the same as what we call in our Bibles, the Old Testament). Read Isaiah 53, Psalm 22, and other passages that address the suffering of the Savior. Then read the Gospels of the New Testament and the Book of Hebrews in the New Testament which explains how Jesus fulfilled what Judaism is yearning for.
