4 But you, brethren, are not in darkness, that the day would overtake you like a thief; 5 for you are all sons of light and sons of day. We are not of night nor of darkness; 6 so then let us not sleep as others do, but let us be alert and sober. 7 For those who sleep do their sleeping at night, and those who get drunk get drunk at night. 8 But since we are of the day, let us be sober, having put on the breastplate of faith and love, and as a helmet, the hope of salvation (1 Thessalonians 5).
The first thing God created was light (Genesis 1:3), which in its very essence dispels darkness, for it cannot help but do so. As “sons of light and sons of day” our very essence also consists in dispelling darkness. We do the things associated with the day and its light. We are spiritually “alert and sober,” doing the things of God rather than the things of the devil.
We are armed for battle against the forces of darkness. [Ten years after writing this epistle, Paul would tweak and expand this metaphor in his letter to the Ephesians (chapter 6).] Our aim is to dispel spiritual darkness wherever we can in our lives and in this world. This is what we do.
Lord, help us This Day to do what we are meant to do. Amen.
