Ephesians 5:8-13 contains some important principles for Christians:
1. We should glow:
"For you were once darkness, but now you are light in the Lord."
(See also Philippians 2:15)
2. We should grow:
"Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth)"
(See also Romans 8:12-13)
3. We should know:
"find out what pleases the Lord."
(See also 2 Corinthians 5:6-10)
4. We should see:
"Have nothing to do with the fruitless deeds of darkness, but rather expose them." (See also Romans 13:12)
5. We should flee:
"It is shameful even to mention what the disobedient do in secret. But everything exposed by the light becomes visible—and everything that is illuminated becomes a light."
(See also Psalm 101:3)
Let's glow, grow, know, see, and flee.
Matthew 5:16 sums it up this way: "Let your light shine before others, that they may see your good deeds and glorify your Father in heaven."
