Luke 6:45

A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.

We can identify whether a person is good or evil from the intentions and motivations of their words and persistent performance; because what they say and do are actually what they think. A good person has good will, conscience, and sense. If they who pursue the truth does something that goes against human virtue or does something evil, they will feel guilty and accused, and people around them can see that they feel guilty and ashamed. However, a wicked person only holds evil thoughts in their mind. No matter how great an evil a wicked person commits, they think that it’s a skill, a talent. 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 even worse, they don’t loathe themselves. They’re even pleased with themselves, thinking 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 are supposed to be. That such behavior is normal. 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 evil people, after we have distinguished them as such, we must abandon them, draw a line between us and them, and not follow them in doing evil. As believers in God, what path we walk, what kind of people we follow, who we really obey, and whom we stand with…all of these are matters of principles. Only by entering the truth and learning how to discern all different kinds of people can we renounce evil.
