Although the title "Rabbi" is a term that gets used today in Judaism, it was also a term that used for Jesus by His followers. It is an appropriate title, because it essentially means, "Master, Teacher". But of course, as Christians, we know that Jesus was more than just a good teacher. He did teach us many things, but chief among those teachings was what He did for us on the cross. He is our Master and we serve by following His example. We serve others and proclaim that great teaching of the Gospel to all we come into contact with.
