But fornication and all impurity or covetousness must not even be named among you, as is fitting among saints.
Let there be no filthiness, nor silly talk, nor levity, which are not fitting; but instead let there be thanksgiving.
Be sure of this, that no fornicator or impure man, or one who is covetous (that is, an idolater), has any inheritance in the kingdom of Christ and of God.
Let no one deceive you with empty words, for it is because of these things that the wrath of God comes upon the sons of disobedience.
Therefore do not associate with them,
for once you were darkness, but now you are light in the Lord; walk as children of light
(for the fruit of light is found in all that is good and right and true),
and try to learn what is pleasing to the Lord.
Take no part in the unfruitful works of darkness, but instead expose them.
For it is a shame even to speak of the things that they do in secret;
but when anything is exposed by the light it becomes visible, for anything that becomes visible is light.
Therefore it is said, "Awake, O sleeper, and arise from the dead, and Christ shall give you light."
Look carefully then how you walk, not as unwise men but as wise,
making the most of the time, because the days are evil.
Therefore do not be foolish, but understand what the will of the Lord is.
