“You are all sons of light and sons of the day. We are not of the night nor of darkness“
You are all sons of light and sons of the day.
Note that Paul does not say, “You are all sons in light and sons in the day” but ”of the light” and “of the day.” The issue is not where they are but who they are. It is not a matter of environment but of origin and source. The Christian lives in the orb of light and day. Status as sons of light and of the day carries privilege.
“Sons of light” denotes that a person partakes of and possesses the character of his origin or derivation just as a child takes after his parent. God characterizes sons of light as to their nature. Christians are inevitably light. Sons of light are also sons of day when light rules supreme.
God deems “all” Christians as light, not just some.
We are not of the night nor of darkness
The coming Day of the Lord is a day of darkness, a day of wrath. Christians will not participate in that day. Paul changes from “you” to “we.” We were sons of the night and darkness.
Christians are inevitably light.
Regardless of the state of the Christian, he is the personal responsibility of the Lord Jesus Christ. Every Christian is a personal representative of the Lord Jesus on earth. We are here for the purpose of glorifying Him through the witness of our life and lips. Every believer is in full-time service, a priest of the Lord Jesus. We are here to represent the Lord Jesus.
We might say, “I have failed Him and do not deserve to serve Him.” However, we represent Him for good or bad. We remain His ambassadors here. We are lights in the world (Matthew 5:14) because He is the “light of the world” (John 1:1-9; 8:12; 9:5). Jesus was the light as long as He was on the earth.
“…that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world…” (Philippians 2:15).
Many Christians do not give out very much light. That is why the world is so dark.
“For you were once darkness, but now you are light in the Lord. Walk as children of light…” (Ephesians 5:8).
God illumines Christians. Some of us give out more light than others. Christians are lighthouses that war against of the shoals of hell and shine light on eternal life.
