For though your hearts were once full of darkness, now you are full of light from the Lord, and your behavior should show it!
For this light within you produces only what is good and right and true.
Try to find out what is pleasing to the Lord.
Take no part in the worthless deeds of evil and darkness; instead, rebuke and expose them.
It is shameful even to talk about the things that ungodly people do in secret.
But when the light shines on them, it becomes clear how evil these things are.
And where your light shines, it will expose their evil deeds. This is why it is said, "Awake, O sleeper, rise up from the dead, and Christ will give you light."
So be careful how you live, not as fools but as those who are wise.
Make the most of every opportunity for doing good in these evil days.
Don't act thoughtlessly, but try to understand what the Lord wants you to do.
