You were darkness once, but now you are light in the Lord; be like children of light, for the effects of the light are seen in complete goodness and right living and truth. Try to discover what the Lord wants of you, having nothing to do with the futile works of darkness but exposing them by contrast. The things which are done in secret are things that people are ashamed even to speak of; but anything exposed by the light will be illuminated and anything illuminated turns into light. That is why it is said:

Wake up from your sleep,

rise from the dead,

and Christ will shine on you.
