Talking the talk vs walking the walk

To me there’s often a huge difference between (a) reading something versus (b) being told something to your face. For instance, a Christian might read the line, “Judge not that ye not be judged,” and they could think to themselves, “Oh, I don’t judge people, I’m good.” But then if you’re with them and they say something bad and you slap them in the face and yell, “Stop judging your sister!,” or, “Stop judging your brother (or your friend),” they will realize that they’re actions don’t line up with their beliefs.
