It's... a passage in the bible, basically not to complain of the speck in another's eye if there's a log in your own. It explicitly calls out hypocrisy.

But I think given you can't very see with a log in one's eyes, it can also mean you can't judge without taking the time to actually look and see, by removing what's blocking your view.

I won't compromise my convictions - but I'll be trying to look before I judge.
