Ephesians 5:8-10

8For 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]

9(for the fruit [the effect, the result] of the Light consists in all goodness and righteousness and truth),

10trying 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].
