Ephesians 5:7-11

So do not participate or even associate with them [in the rebelliousness of sin]. For once you were darkness, but now you are light in the Lord; walk as children of Light [live as those who are native-born to the Light] (for the fruit [the effect, the result] of the Light consists in all goodness and righteousness and truth), trying to learn [by experience] what is pleasing to the Lord [and letting your lifestyles be examples of what is most acceptable to Him—your behavior expressing gratitude to God for your salvation]. Do not participate in the worthless and unproductive deeds of darkness, but instead expose them [by exemplifying personal integrity, moral courage, and godly character]
