My guess is that her name is from a statement of faith:
Jesus does all things for the good of those who love him. (Assuming) She is a devout Christian, then her faith is important to her and she wanted to somehow communicate that subtly on her online steemit presence without having to shout "hey, I'm a Christian".
And anyway....honestly! Who's gonna choose a name like "allforthebad" or "noneforthegood"
Those would make absolutely no sense. So she really only had one possible Steemit name! Really!
Peace
Funny! :D What about allforthebest, allfortheawesome, allfortheamazing, or maybe too high? allfortheaverage, allforthemediocre Good guess, thanks!
