He has sent many messengers and created a world filled with signs for people to reflect. Why would someone acknowledge His existence, but refuse to worship Him and to obey the commands He has told people to obey (or, the commands people think he has made known)?
For the same reason that somebody in North Korea, who recognises the existance and absolute power of Kim Jong Un, might not worhip him.
If tomorrow I become convinced that the god of the bible exists, I'ld also have quite a big problem with "worshipping" an entity that I consider to be an authoritarian, dictatorial, homophobic, mysogenistic, barbaric, immoral monster.
Next to that, I also have a problem with "worshipping"
anything, full stop. The very act of worship is not something I consider particularly helpfull or usefull for anything.
And if I wouldn't think that, I'ld still say that worship is something that needs to be earned, much like respect. And simply holding absolute power, is not one of the parameters that gains you such.
Kim Jong-Un has absolute power in North Korea, but his actions don't really make him worthy of respect - let alone worship - right?
Curiously, he too demands of his subjects that they worship him.
In fact, it seems to be the case that entities that
demand worship, actually never deserve or earned it. And in fact, in most cases - if not all - the opposite seems true........The engage in behaviour that pretty much exclude them from being worthy of respect or worship.
They are mass murderers, oppressors, intolerant (racist, sexist, fascist, homophobic,...), narcistic, etc.
Because of this... whenever I hear of an entity, being a god or otherwise, that
demands to be worshipped - all kinds of alarm bells go off. And upon closer inspection of the backstory of such entities, it always turns out that those alarm bells are justified.
The bottom line here is simply:
might, does not make right.
