For though once your heart was full of darkness, now it is full of
light from the Lord, and your behavior should show it! Because of this
light within you, you should do only what is good and right and true.
Learn as you go along what pleases the Lord. Take no part in the worthless
pleasures of evil and darkness, but instead, rebuke and expose them.
It would be shameful even to mention here those pleasures of darkness
which the ungodly do. But when you expose them, the light shines in
upon their sin and shows it up, and when they see how wrong they really
are, some of them may even become children of light! That is why God
says in the Scriptures, 'Awake, O sleeper, and rise up from the dead;
and Christ shall give you light.'
So be careful how you act; these are difficult days. Don't be fools;
be wise: make the most of every opportunity you have for doing good.
Don't act thoughtlessly, but try to find out and do whatever the Lord
wants you to. Don't drink too much wine, for many evils lie along that
path; be filled instead with the Holy Spirit, and controlled by him.
Talk with each other much about the Lord, quoting psalms, and hymns,
and singing spiritual songs, making music in your hearts to the Lord.
Always give thanks for everything to our God and Father in the name
of our Lord Jesus Christ.
--Ephesians 5:8-19, The Book
