And He (Jesus) will give you a new name

Many of the Bible legends were given a new name. Jacob was called Israel. Saul was named Paul. Simon was called Cephas (Peter). A new name cannot come to an old person. If you are still loyal to self and not abondoned to Christ, there is no use giving a new name to an old person.
Jesus wants to call you Christian, but to do this, we must be His followers.
