Why should anyone even want a relationship with God?

[FallentoReason]

I think we may have been talking about different things without realising it.

Worship

If a theistic god were in fact real, then that most likely means that it demands my worship because the book says so.

Answering the question you just brought up; no, I wouldn't worship my parents even if they asked me to. They are mortal beings like me.


Being Grateful

If a god really does exist, then I'm grateful for making this universe possible.

I'm also grateful that my parents decided to start a family. I guess they do deserve that much.

So when it comes down to it, being immortal is somehow the deciding factor as to whether or not something is deserving of worship? You can owe your life to something, no worship - something can make demands, no worship - but throw immortality in and you bend the knee at that point? I can show you many organisms that you do not owe your life to (not that this matters, apparently), that do not demand worship (not that this matters, apparently) but -are- biologically immortal. Should you and I start piling up stones in their honor?

What organisms are immortal?

Or do we have a scenario where you would require a creator who demands worship and happens to be immortal? Is it a package deal? If so, what about that package leads you to conclude that the hypothetical possessor of these attributes is worth your bending the knee?

It's most definitely a package deal. That might sound somewhat twisted but unfortunately Holy books have a lot of twisted stuff in there. I'm all about truth though and IF one of them were to be the Ultimate Truth of the Cosmos then it means that the reality is that you have to get down on your knees and worship that dictator.
