[I]t is hardest to give grace to grace killers. You know what I mean? And I say that because when I read blog posts similar to the one referenced, I know that I struggle with anger, and indignation with this sense of “YOU’RE DOING IT WRONG!” I struggle to remind myself of this, that I should give grace to the people who fail to use it. To be gentle in one’s criticism.
I don't know anything that has brought me up so short as that. I think practicing it might just be the work of a lifetime.
