"I ate 7 donuts this morning"
"I lied to my gym partner and went to the movies instead"
"I hooked up with my ex-boyfriend again. Don't judge me. Judging people is wrong. Christians don't judge."
When we say "don't judge me" though, what we're really saying is "let me off the hook. I have no interest in facing up to my own foolishness, so don't call me out. Don't hold me accountable for my own actions, please, because then I would actually have to deal with it."
Just because you don't judge someone doesn't mean you can't still hold them accountable for their actions. If I read your latest blog post or get to know your newest "girlfriend" and tell you that I think you can do better, I'm not judging you, I'm holding you accountable to the standard I know you can, and want to uphold.
We will often give up what we want most for what we want in the moment, which is why we have accountability partners and friends in the first place.
Of course, I can't just go around "holding everybody accountable" without them asking me or even knowing who I am. This is judging, and something far too many people (especially Christians) take part in. But if a trusted friend has asked for your help, whether it's in their art, self discipline, or their battle against sin, then you have a responsibility to hold them accountable, even when they hate you for it. They may try to pull the "don't judge me" card, but really they're just asking you to take it easy on them. Don't. Do what you need to do in order to fulfill the role they have given you in their life.
Don't judge me. But please, please hold me accountable.
