The world is a dangerous place.

      When we refuse to judge, we render ourselves powerless. We can’t tell people that they have done a good job, and we can not tell evil people to cool it!  I am so grateful for the Corrie ten Booms and the Irena Sendlers of this world. Their willingness to judge evil saved many lives.  To see so many Christians tell me that I should quit calling out the evil I see hurts my heart.
Not only is Matthew 7:1 taken out of context, but it simply doesn’t make sense to refuse to judge. When you pick out a babysitter for your kids, would you let someone who looked like they sold their body for crack baby sit, or would you prefer to miss work until you could find someone else to take care of your kids?

If you are at a store and see someone smack a kid so hard that they get a split lip and a bloody nose, that is something that a good person CAN NOT ignore! For the good of society sometimes you have to judge!
Now I realize that these cases are extreme, but I believe they prove that there are cases where judging is nessesary.
