The quote as given at the discussion begining is oddly worded and grammatically confusing. It probably means "we accept the world that we have been given".
In this case, I agree with others who have said we should accept the world as it is, and not waste time wishing that it were something else...which it isn't.
We sometimes wish for things to be different from what they really are. Such wishful thinking never works.
I remember hearing a brilliant speaker respond to an audience member who was expressing this type of sentiment...wanting things to be other than they really are. The speaker said to the woman, "yes, madam, I see your point. And even if it isn't true, it very easily could be, couldn't it?!" The response politely appeased the woman, while making the point to the rest of the audience of the futility of the woman's hope.
