Contrary to popular opinion, the most often quoted passage of Scripture may not be John 3:16. I believe, rather, it is regularly Matthew 7:1 “Judge not, lest ye be judged.” Moreover, it often comes from those who have little, if any, regard for God’s Word, especially His law. Their judgments are grounded in their own feelings, likes, and dislikes. This really is not surprising, in that God’s law—the standard by which we are to judge—is really the target of such comments, revealing a disregard for the whole counsel of Scripture.
We are not forbidden to judge; we are commanded to use God’s standard when we judge. R.J. Rushdoony notes that to avoid righteous judgment is to sin and that to prevent righteous judgment is to trifle with God’s law and to incur His judgment. Rushdoony also notes, “I have learned, over the years, to be very, very suspicious of people who act as if our Lord said only, ‘Judge not.’ Such people are all too often hiding some sin and are badly in need of righteous judgment.
