Paul said that they should not do evil things like fornication, involved with impurity, passion, evil desires, greed, and idolatry. The wrath of God was coming to those disobedient ones who practiced such things. These were the things that they once did in their former old lifestyle. Now it was time to get rid of that old life of anger, wrath, malice, slander and abusive language. They were not to be liars. They had to strip themselves of their old life and its practices. Their old lifestyle had to die.
