The Central Message of Christianity

For God so loved the world...

John 3:16

I have a question to ask my readers:  What is the core message of Jesus Christ?  Or, to put it a different way, what is the central message of Christianity?

I don't think I have ever tried to analyze the Gospel in quite that way.  However, when visiting the God is Imaginary website and trolling down through the author's 50 proofs that God is not real, I found Proof #21: Understand Jesus' Core Message.  When I clicked on the link, this is what I read:

Take a moment to think about this statement:  

 "Hello, my name is Jesus. I love you deeply. I have loved you since you were conceived in the womb and I will love you for all eternity. I died for you on the cross because I love you so much. I long to have a loving personal relationship with you. I will answer all of your prayers through my love. But if you do not get down on your knees and worship me, and if you do not EAT MY BODY and DRINK MY BLOOD, then I WILL INCINERATE YOU WITH UNIMAGINABLY TORTUOUS PAIN IN THE FIRES OF HELL FOR ALL ETERNITY BWAH HA HA HA HA HA!" 

Yes, this is the central message of Christianity [based upon John 6:53-54 and Mark 16:16].

I was appalled that the author of this website could possibly think that the paragraph above represents the vital core of Christ's message.  Most likely, he doesn't think that at all, but throws it out there because it is inflammatory (and insulting, come to think of it).  Now I challenge my readers:  what do you believe the core of Christ's message to be?  I look forward to reading your comments, and will post my synopsis of the Gospel tomorrow.
