Without it being personal it sounds generic and subliminal; that line has zero heat and we've heard 'arms to short to box with god' a zillion times as a bar. Where's the discussion on how Kendrick is never ever outside and is a pure studio creation, etc. Imho he should have just dropped the album without this track and kept it moving. No one wants impersonal beef.
Alphonse says it better:
I mean, you asked for the bars that say he ain't outside, they are provide to you, then you are saying it didn't happen, all in defense Kendrick verse which was not a potent diss towards Cole in any way.
"Box with god" isn't the bar- it's just a reference to other diss tracks. The bar is pointing out that Kendrick lives his life in a constant facade.
Aphonse ain't saying nothing about the first verse that I haven't said here. But like I said, I'm not one that has an issue pointing out shortcomings.
You mention no one wants impersonal beef, but where are the comparative personal shots at Cole?
