In the world, we have different kinds of people. We have people who are really hot-tempered. We have people who are lustful. We have people who are thieves. We have people who delight in taking other people’s blood. Some are liars. Some are criminals. There are several kinds of wicked people in the world.
These wicked people are wicked because the devil has encoded those wickedness into their generations. Wickedness came from the nature of the devil which entered into humanity after the fall of man in the garden of Eden. The devil give us a wicked heart since then. This is why there's much wickedness in the world.
There are people who are long-suffering. There are those who are peaceful. There are those who are loving. There are those who are gentle and meek. These people are those who have the Holy Spirit in their hearts. The Holy Spirit produces these qualities in them. No one can be good or gentle or loving or long-suffering without the Holy Spirit.
