Why your exsistence is more worthless than you previousy thought it was.

[Sword of Christ]

The trouble is, you don't actually have any good reasons to believe

If I didn't then I wouldn't believe in it so I'm fairly sure that I do, certainly I'll know more about the good reasons I have than yourself.

nor any good arguments to support your belief.

Masses of very good arguments, not scientific arguments but I'm a bit tired of having to explain that you can't demonstrate Gods existence through science/direct observation. For scientific arguments the best you can do is go into the fine tuning business. It could still have done all this by pure coincidence but I'm not sure how that's more likely or less extraordinary than the alternative, given everything that was involved and the sheer amount of order and complexity of it.

Every justification for every theist claim I've ever encountered can be easily whittled down to "I believe it because I want it to be true".

Atheist arguments against Gods existence keep referring to science but most theists aren't trying to argue against science or claim there is any scientific proof of God or that there ever can be such a thing. Science is limited to what you can see/detect and that's it.

If there is no actual need for a creator

You will need something eternal beyond the universe to cause the universe to exist in the first place if it's finite in itself. That's the bare minimum of what you need.

and no creator ever makes himself known to anybody in any measurable way

The point being made is that he made himself "known" to someone at some point and we have the revelation from that. Differences of opinion on exactly what was revealed to who and when there are different faiths and interpretations.

You don't base your beliefs on anything but your own desires and your faith in them is entirely driven by self-interest.

A bit of a baseless accusation I don't see where you're getting this from.

We tailor our expectations to match reality. You struggle to force reality to confirm your expectations.

There is no need to force God into reality if God is the whole entire basis for reality in the first place. What do you think the basis of reality is?

As the last 500 years has so artfully demonstrated, the more people know, the more difficult your job gets.

A little bit of knowledge takes you away from God and a lot of knowledge brings you closer to God.
