One thing many JW's could do was quote Jesus, although whether or not they lived up to the so-called 'christian ideal' is questioned by most of us. Conversely, many others who call themselves christians are much nicer people! They love, they are generous, charitable and willing to give - but they are unlikely to be as familiar as we are with the details of Jesus life and ministry as recorded in the Bible.
I don't have a problem with that, it's what people do that matters!
But there's my point. Isn't Jesus becoming less and less relevant? The vicar or priest may focus on his compassion or humility once a week but the point is that a moral lesson has been taught. Is Jesus simply becoming a vehicle for this moral education?
Then you have people like Carl Sagan and Richard Dawkins who promote a very moral and philanthropic approach to life that is completely divorced from Jesus - but it still works.
As time meanders onwards, will Jesus still be relevant in the year 3000?
