This passage has suffered significant abuse by the live-and-let-live crowd. They particularly like to isolate verse 1, “Judge not, that ye be not judged.” (Isn’t it amazing how many people have memorized that verse?) Pulling it completely out of the context in which Jesus spoke these words, they use it to criticize those who take a stand for righteousness among those who flaunt their sin. The point here is that the Pharisees practiced a false, high-profile, in-your-face righteousness. The Pharisees were, in fact, corrupt - not righteous. That’s the context in which Jesus accused these Pharisees regarding their quick-to-judge practices. In fact, Believers are to take a stand for righteousness and shun Believers who practice sin. You can clearly see that principle in I Corinthians 5:11 (see notes), “But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.” But be careful; make certain that, while you’re separating yourself from Christians practicing wickedness, you don’t have glaring inconsistencies in your own Christian testimony.
Thank you for putting that into the proper context.
