Verse 4 says: “But you, brethren, are notin darkness, so that this Day should overtake you as a thief.” Notice againthe contrast. In verse 3 Paul spoke about “they” and “them.” Nowhe says: “But you, brethren.” Why is there a difference? Becausebelievers belong to Christ. Paulsays in verse 5: “You are all sons of light and sons of the day. We are notof the night nor of darkness.” Throughout Scripture, light and darkness arepictures of two completely different spiritual conditions. Darkness representssin, ignorance, and separation from God. Light represents truth, holiness, andlife in Christ. Jesus said in John 8:12: “I am the light of the world. Hewho follows Me shall not walk in darkness, but have the light of life.” Whenwe trusted Jesus Christ, we were brought out of spiritual darkness and into Hiswonderful light. Peter described believers as those whom God has called “outof darkness into His marvelous light.” SoPaul says: “You are children of light.” That tells us who we are. Andthen verse 6 tells us how we should live: “Therefore let us not sleep, asothers do, but let us watch and be sober.” In this verse, sleep is notreferring to physical death as it did in chapter 4. Here sleep picturesspiritual carelessness and indifference. Paul says, “Don't live as thoughnothing important is happening.” Wake up spiritually. That is a messageChristians need in every generation. It is possible to know Christ and stillbecome spiritually sleepy. We can become comfortable. We can lose our sense ofurgency. Our prayer life can become routine. Our Bible reading can becomemechanical. We can become so occupied with this present world that we forgetJesus is coming again. Paulsays: “Let us watch.” To watch means to stay spiritually alert. Jesusrepeatedly used the same word when speaking about His return. He said: “Watchtherefore, for you do not know what hour your Lord is coming.” Watchingdoesn't mean standing outside staring into the sky. Watching means living everyday in readiness. It means keeping short accounts with God. It means staying inHis Word. It means maintaining a faithful prayer life. It means using ouropportunities to serve Christ. It means refusing to become comfortable withsin. ThenPaul says: “And be sober.” The idea is being clear-minded, disciplined,and spiritually self-controlled. A sober Christian sees life from God'sperspective. The world says, “This life is all there is.” The Christian says,“Eternity is coming.” The world says, “Live for yourself.” The Christian says,“I belong to Christ.” The world says, “Gather everything you can here.” Jesussays, “Lay up for yourselves treasures in heaven.” Being a child of lightshould make a difference in how we live. Ephesians 5:8 says: “For you wereonce darkness, but now you are light in the Lord. Walk as children of light.” NoticePaul doesn't say we merely have light. He says we are children of light. Ouridentity should affect our conduct. Sometimes we approach the Christian life bysaying, “Here is a long list of things I shouldn't do.” But Paul startssomewhere deeper. He reminds us who we are. You belong to Jesus. You are achild of God. You are a child of light. Therefore, live like who you are. Maybetoday would be a good time for a spiritual wake-up call. Has something causedyou to become spiritually sleepy? Have you lost some of the excitement you oncehad about serving the Lord? Have the things of this world crowded out yourawareness of eternity? Heavenly Father, thank You that through Jesus Christ You have brought usout of darkness and into Your marvelous light. Help us to remember who weare—children of light and children of the day. Guard us from becomingspiritually sleepy or careless. Wake our hearts to the reality of eternity.Help us to watch, to be sober, and to live every day in fellowship with You.May the light of Jesus shine through our lives so that others may see Him inus. In Jesus’ name, we pray. Amen.
