Do you ever feel threatened by not following instructions or "orders" from other gods? What if there are horrible consequences for not paying homage to Kali? Shiva? Which deity should I be most concerned with angering by not obeying it's directives or adhering to it's tenets? None of that causes me to lose sleep at night. It's why this thread is in a debate section, I suppose.
What if Cthulhu is actually real? Are we all doomed?
It depends on how that 'other' god would reveal itself to me. If the god does not reveal itself to me, then I don't even know the law and I don't know the consequences. And. The revelation would need to include some sort of proof that the god actually has authority over me.
Lacking that, what ever transgression results is out of ignorance. And... ignorance is bliss. No I would not lose sleep over it either. But that doesn't mean that there are no consequences. All it would mean for me, is, if there is some sort of divine court, or trial, I can plead ignorance and beg for mercy. Or I could protest loudly and proudly. Or some combo.
If there is no court, no trial, no justice, then, it doesn't really matter. It will be, what it will be. And I'm back to not losing any sleep over it and doing my best. And that leads back to the encouragement you wrote about.
