It's just like the word "marriage" and means whatever you want it to.
Or like the word "Red" in politics meant "Communist" and now means "Republican".
Or "Gay" now means "homosexual" (but you can't say "homosexual" any more).
You also won't hear many self-identify as "Communist" now.
That word was changed to "liberal" for a while, but now they call themselves "progressive".
It's tricky, but I find it's helpful to read Isaiah 9 substituting "America" for any references to "Israel" and my situational awareness and understanding improves.
Gr8 post . I appreciate your analysis.
