True Knowledge of Human Nature

Because those people refuse to keep in mind the true knowledge about God, he has given them over to corrupted minds, so that they do the things that they should not do. They are filled with all kinds of wickedness, evil, greed, and vice; they are full of jealousy, murder, fighting, deceit, and malice. They gossip and speak evil of one another; they are hateful to God, insolent, proud, and boastful; they think of more ways to do evil; they disobey their parents; they have no conscience; they do not keep their promises, and they show no kindness or pity for others. They know God’s law says that people who live in this way deserve death. Yet, not only do they continue to do these very things, but they even approve of others who do them.

Romans 1:28-32

What human nature does is quite plain. It shows itself in immoral, filthy, and indecent actions; in worship of idols and witchcraft. People become enemies and they fight; they become jealous, angry, and ambitious. They separate into parties and groups; they are envious, get drunk, have orgies, and do other things like these. I warn you now as I have before: those who do these things will not possess the Kingdom of God.

Galatians 5:19-21
