On theism, why do humans have moral duties even if there are objective moral values?

[Pnerd]

And I have to ask, what part of "rewarding in itself" did you not understand?

The "rewarding in itself" part. Does it mean rewarding as a secular humanist would understand it, that is, it simply feels good to help someone and it feels good because god makes us feel good? Previously I did not consider the "god making us feel good" part.

Speaking of destroying your logical faculties, separating a compound clause and treating them as independent clauses doesn't (sic) speak highly of your faculties.  This is nothing but a reading comprehension fail.

Ignoring the tu quoque nature of the first sentence, I admit that it might very well be a reading comprehension fail on my part. But I can't be sure unless I know which sentence or clauses (and by whom) you're referring to. Can you quote the sentence and let me know which clauses I butchered just so I can improve my English grammar (and I'm not being sarcastic here)?

I might excuse it except...

Fortunately, I'm not going to lose any sleep over that.  

I'm sure your native tongue has the same rules for compound clauses as English.

I don't really know the rules of compound clauses in English. But I'm curious as to how much you know about my native tongue for that level of certainty (on your part) to be justified.
