That's a very pertinent and quality question. The short answer is that every genuine Christian serves and worships a Man who was born a Jew and will return as the 'Lion of the Tribe of Judah'.
I promise you I will give you a proper and full answer to such a good question, but as I am taking my daughter to catch a plane at 5am tomorrow then I'd better sign off now and get back to you across this Easter weekend.
Have a good one
