I'm with Zeke simply because it makes sense. I belong to no "organized religion" simply because they all seem more interested in the organization than the message. Analyzed, Jesus' teachings make a great deal of sense as a method for living with each other with reduced friction, always a good idea. If I am wrong, I will not know it, if the deniers are wrong they are in for a pleasant surprise.
BTW I much prefer Rabbi Hillel's version "That which is distasteful to you do not do unto others, this is the whole law the rest is mere commentary."
