Christian "purpose" and "meaning" in life.

[Deepthought]

Most theists that I've known and I think most of the theists on this board believe that God gives their lives meaning.
I usually just laugh inside, knowing that it is simply self delusion, but I just saw this cute cartoon and it struck me that if we are simply god's pets and our purpose is simply to praise him for all eternity, then it's not reassuring to have such a purpose, it's degrading. Check out this cartoon and see if you agree.

It must be a vain God that requires to be praised/worshipped all the time! My parents gave me life but I don't worship them or praise them with every other breath. Instead of spending time praising God, the theist spent more time helping other human beings, the world would be a a little bit better.
