Ephesians 5:15

15.See then. If believers must not neglect to drive away the darkness of others by their own brightness, how much less ought they to be blind as to their own conduct in life? What darkness shall conceal those on whom Christ, the Sun of righteousness, has arisen? Placed, as it were, in a crowded theater, they ought to live under the eye of God and of angels. Let them stand in awe of these witnesses, though they may be concealed from the view of all mortals. Dismissing the metaphor of darkness and light, he enjoins them to regulate their life circumspectly as wise men, (160) who have been educated by the Lord in the school of true wisdom. Our understanding must shew itself by taking God for our guide and instructor, to teach us his own will.
