Christians follow the teachings of Christ, hence the name. Jesus gave his followers a new commandment ‘Love one another as I have loved you.’ He also gave them a new covenant which takes over from all and any covenants from the Old Testament, ‘This is my blood of the new covenant, which is shed for many.’ Christians remember this new covenant when they take Holy Communion. What is written in the Old Testament is interesting, and historical, but not relevant to the teachings of Christ and the followers of Christ, because Christ’s teachings supersede the Old Testament.
People are entitled to believe as they wish, but it is unacceptable to try to ‘prove’ that others are wrong in their beliefs unless they are using those beliefs to commit evil. Evil is committed in the name of religion, but not by true Christians in these days.
If the OT isn't relevant to Christianity why do Christians use it as evidence that JC is the messiah. Isaiah is often used as evidence but it's not the only source from the OT. Various books and verses are used to support Christians claim that JC was the messiah. They talk about the virgin birth, Bethlehem, that he would come from the tribe of Judah etc.
Talking of Bethlehem. Did you know there were two Bethlehems? One, the one Christians believe is where JC was born, was known as Bethlehem of Judea. This Bethlehem is about 96 miles from Nazareth. However, there was another town called Bethlehem of Zebulun which was about 10 miles from Nazareth. Which was the most likely place for a heavily pregnant woman to be able to travel? But the OT prophecy had to be fulfilled so it had to be Bethlehem of Judea.
Even the Gospels don't all say that he was born in Bethlehem of Judea or any Bethlehem.
