Ephesians 5:5-6

5You can be sure about this: If anyone has sex in a wrong way, that person does not belong to God's people. Nobody who does any kind of disgusting thing belongs to God's people. People who want many things just to please themselves are like people who worship an idol. They also do not belong to God's people. Nobody like that belongs to the kingdom where Christ and God rule. They will not receive the good things that God has prepared for his people.

6Do not let anyone have a chance to deceive you with a false message about those kinds of bad things. God will certainly punish people who do not obey him.
