According to David Hutchison, Christians must identify certain behaviors as sinful and we must judge in at least three other senses which includes evaluating the teachings of those who claim to speak in the name of the Lord. He reminds us that “There are contexts in which Christians must judge, but we must judge justly.” Now to his piece over at Theology Matters:
Standing for biblical truth elicits many negative responses from those outside the church as well as from some within. This is not surprising since Jesus told His disciples that they would be hated on account of Him (John 15:18-19, 1 John 3:13). While we may simply shrug this off as part of the reality of life, what is more challenging to navigate is the suggestion that by using the word “sin” for certain activities, we violate Jesus’ command not to judge. In popular sentiment, “do not judge” means that one cannot say any behavior is wrong. This understanding is pervasive, but it is severely flawed.
There are pitfalls of judging that we must avoid, but doing so does not mean we cannot call sin what God has called sin. In fact, if we refuse to do so, we act as God’s judge, claiming that our perspective on the situation trumps His own. Similar to the rejection of God’s testimony in 1 John 1:10 and 5:10, this is tantamount to calling God a liar. We must call sin, sin, but we must also remember that God knows all of the details of the situation. We never will, and we often lack key information. As John 7:24 notes, we must not judge by mere appearances but must make a just judgment. If we wish to do so, we are wise to listen well and listen long, remembering the folly of giving an answer too quickly (Proverbs 18:13).
