I have heard that the word christian derived from the followers of Christ looking and acting so much like Jesus Christ that they were then called christians (which meant in those days "little christ"). A christian then is a "little christ". One whose life is marked by true repentance and the fruits of the spirit. People who used to know you sould be able to see someone different and when they try to charicterize you're new being they should think of Jesus Crist your personal Lord and Savior.
