This verse points out some principles of discerning good from evil. We can discern whether a person is good or wicked from the intentions and motivations of his words and persistent performance because what he says and does is actually what he thinks. A good man has good will, conscience, and sense. If he who pursues the truth does something that goes against human morality or does something evil, he will feel guilty and accused, and people around him can see that he feels guilty and repentant. However, a wicked person has evil thoughts in his mind. No matter how great evil a wicked person commits, they think that it’s a skill, an ability. They think it proves that their methods are superior, that they’ve achieved their goal, and that they’re better than others. That’s why they don’t have remorse, and worse still, don’t loathe themselves. They’re even pleased with themselves, think that they are more capable than others, and look down on others. Such people are wicked people. When they do evil, wicked people don’t have remorse or have a guilty conscience. They just like evil. They think that’s the way humans ought to be, that such behavior is normal. So people can’t see their repentance and changes. Just as God says, “Those who genuinely believe in God are those who are willing to put God’s word into practice, and they are those who are willing to practice the truth. Those who can genuinely stand witness for God are also those who are willing to put His word into practice, and they are those who can genuinely stand on the side of the truth. Those who employ trickery and who do injustice are all people who have no truth and they all bring shame on God. Those in the church who engage in disputes are Satan’s lackeys, and are the embodiment of Satan. This kind of person is too malicious. Those who have no discernment and are incapable of standing on the side of the truth all harbor evil intentions and tarnish the truth. These people are even more so typical representatives of Satan; they are beyond redemption and it goes without saying that they are all objects to be eliminated.”

When we can distinguish between a good person and a wicked person, we should treat different people with corresponding principles. If good people who pursue truth have committed a transgression or exhibited any corruption, we should assist them with love and must not suppress, exclude, or define them as hopeless ones, even though they have prejudices or make some judgment about us. As for wicked people, after we have distinguished them, we must abandon them, draw a line between us and them, and not follow them to do evils. As believers in God, whatever path we walk on, what kind of people we follow, whom we should be obedient to and whom we should stand with, are the matters of principles. Only by gaining the truth and learning how to discern all kinds of people can we shun evil.
