Thiests - Assuming God exists, why should we worship him?

[Captain Scarlet]

1. Luckily most of Christianity believes in the trinity therefore Jesus of Nazerath isn't God the Father, and therefore not an issue. However if you're arguing if Jesus knew that he would die and then return to the Father, then yes he did.
2. Once again using only the material 5 senses is limiting the world to a materialistic view, which isn't mine. Love is more that what you can see, it's what you can't. It's intuitive and instinctual. No one taught you or I what love is or how to love, it's learned, not in our nature. Believe in love at first site? Love is perceived becuase of some kind of input or event, yes I agree, but if love were only based off seeing the object of your love or talking to them, how could you ever long or love someone over a distance? I think you're trying to overly-mechanize love.
3. It's not like a members only jacket , it's available to everyone. It's just like any relationship or covenant, it has 2 sides. Therefore by the strictest definition it's not unconditional, it has at least the condition of acceptance.
4. I'm glad that 99.9% of the Earth won't kill us. Does that make the Earth an anomally? What do you think is the reason for the disparity that 99.9% of the Universe would destroy life but the very being that ponder life have life and live there?
5. Yep those are horrible, luckily Jesus was the fufillment of the OT. Not to abolish it, but to teach us the true meaning of the laws and turn laws of condemnations into the path to life.

A complete response as ever Tack but hardly convincing
1. So we agree there was no sacrifice then, so why did you say there was?
2. Hardly, but I don't mystify it either. Stop the physical processes and love stops. Just look at the unfortunate cases of brain injury where husbands personalities have changed and the love between 2 devoted people dies. If love is immaterial it should survive, and this argument carries as much weight as substance dualism (which to me just seems like casusistry). You cannot name one example in reality where love exists outside of a physical process, except by begging the question on a god/s and putting that to the heart of you premises.
3. Quite so. And how Christians aren't happy until we believe it too. But still considering this is a truth claim it is remarkable that a god cannot provide enough evidence to move say a Hindu to atheism let alone christianity. The simplest explanation is that religions are natural, cultural phenomena.
4. In short no. It makes Earth part of a natural, material world. The processes which made earth are observed and support the theory; as yet the best explanation we have, needing no additional comments, but more research. You have avoided the question around why maroon us on this planet, and that needs an explanation.
5. The theological backing for that statement is beyond my understanding so I am going to plead ignorance. My initial sense of it is, it feels like spin. But then again that seems to be theologies purpose.
6. You did not counter the logical contradiction of worship.
