Ephesians 5:13-17

But everything exposed by the light becomes visible – and everything that is illuminated becomes a light. This is why it is said: ‘Wake up, sleeper, rise from the dead, and Christ will shine on you.’ Be very careful, then, how you live – not as unwise but as wise, making the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is.
