Most or all people are good. So they say. Actually, humans are basically evil. The Bible says that man be inclined toward what is bad from his youth up. (Genesis 8:21) The human heart is treacherous, who can know it? (Jeremiah 17:9) All men have sinned and fall short of God's glory. Men are basically evil.
Comforter is not saying that people are totally depraved. They are not. We are made in God's image and we retain a touch of that image even while sinful. But all humans are inclined toward evil because of Adam and Eve. Therefore I do not trust this world and the bad advice that worldly counselors often give. It is simply wrong to believe that we just have to accept people as they are, warts and all, when it comes to morals. Christians do no such thing. Drunks, homosexuals, fornicators, greedy persons, revilers or adulterers will not inherit God's kingdom. Christians need to resist sin and every semblance of evil.
The Enlightenment teaching of inherent goodness is a fallacy. Wake up and recognize.
