1 We then, as workers together with Him also plead with you not to receive the grace of God in vain. 2 For He says: “In an acceptable time I have heard you, and in the day of salvation I have helped you.” Behold, now is the accepted time; behold, now is the day of salvation” (2 Corinthians 6:1–2, NKJV).
Christians are repeatedly warned in the Scriptures to beware of falling away from God, His grace, and the faith (Heb. 3:12-13; Gal. 5:4; 1 Tim. 4:1; James 5:19-20). Embedded in this warning in 2 Corinthians 6:1 is a call to urgency by recognizing “the accepted time” and “day of salvation” and diligently receiving and standing in God’s grace (2 Cor. 6:2). Consider the days appointed by God that urge us to respond to God’s grace in faith and be saved in Christ. (1) The day of salvation (2 Cor. 6:2). This day is the gospel age. Salvation is available to all who believe (John 1:12; Mark 16:15-16; Rom. 10:8-13; Acts 2:36-38). God appointed this time to believe and obey the gospel for salvation and eternal life (Gal. 4:4). (2) The day of death (Heb. 9:27). Death is the great equalizer (Eccl. 2:14; 9:2-3; 12:6-7). Jesus releases the children of God from the fear of death (Heb. 2:14-15). Death is a great incentive to be a Christian and live by faith, not fear. (3) The day of judgment (Acts 17:31; Heb. 9:27). God calls us to repent because He will “judge the world in righteousness” by His Jesus Christ. God has confirmed a day of judgment is coming by raising Jesus from the dead. Therefore, God commands us to repent (Acts 17:30). We do not know when we will die or when the day of judgment will happen. But we know “now is the day of salvation.” Believe and obey Jesus to be prepared for the day of your death and judgment (2 Cor. 5:10).
4 But you, brethren, are not in darkness, so that this Day should overtake you as a thief. 5 You are all sons of light and sons of the day. We are not of the night nor of darkness. 6 Therefore let us not sleep, as others do, but let us watch and be sober. 7 For those who sleep, sleep at night, and those who get drunk are drunk at night. 8 But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. 9 For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, (1 Thessalonians 5:4–9, NKJV)
Christians (children of God) are children of the day. Therefore, we are to live watchfully and soberly in the light of truth. The contrast to the inebriation of darkness is easy to understand. Being “of the day” (v. 8) means living soberly in faith, love, and the hope of salvation we have in Jesus Christ. Yet, more and more Christians are partaking in the less than sober practice of drinking intoxicants. Defending “social drinking” of intoxicating beverages as a Christian’s liberty embraces the very thing Paul used to warn us against losing our spiritual alertness. Rather than justify the incremental loss of self-control and the corresponding loss of sharpness, we must refuse even the beginning of this activity associated with darkness (Eph. 5:18; 1 Pet. 4:3).
3 Jesus answered, “Neither this man nor his parents sinned, but that the works of God should be revealed in him. 4 I must work the works of Him who sent Me while it is day; the night is coming when no one can work. 5 As long as I am in the world, I am the light of the world.” (John 9:3–5, NKJV)
The diligence with which Jesus labored is a model of zeal, endurance, and accomplishment. As He prepared to heal a man who was blind from birth, He explained the principle which drove Him each day. He had been given work to do by His Father (who sent Him to the earth). His time on the earth was limited, and so He diligently went about doing His Father’s work (which was teaching the gospel and showing Himself to be “the light of the world” – the Christ, the Son of God). Just as the Father gave the Son work to do, Christians are “created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them” (Eph. 2:10). With Jesus as our model, let us be zealous to walk in (do, practice) the good works of God each day, by living soberly, righteously, and godly (Tit. 2:11-12). Night is coming for us all, when our time to labor for the Lord will end. So, as long as we have today, let us be diligent children of light who do the Father’s will, and “through faith and patience inherit the promises” (Heb. 6:9-12).
5 You are all sons of light and sons of the day. We are not of the night nor of darkness. 6 Therefore let us not sleep, as others do, but let us watch and be sober. 7 For those who sleep, sleep at night, and those who get drunk are drunk at night. (1 Thessalonians 5:5–7, NKJV)
The return of the Lord will not overtake Christians suddenly and unexpectedly, because we “are not in darkness” (1 Thess. 5:4). Paul uses light and day to describe the moral readiness of Christians concerning the coming of Jesus. What does it mean to be “sons of light” and “sons of the day?” The gospel called us out of sin’s darkness (1 Pet. 2:11). By the redemption we have in Christ we have been delivered from the power of darkness and conveyed into the Son’s kingdom (Col. 1:13). We used to live in the darkness of sin, “but now you are light in the Lord. Walk as children of light” (Eph. 5:8). Darkness and night describe the moral slumber of living in sin. Just as we are unaware of our surroundings in sleep, the darkness of night gives cover to sin and its excesses. We must refuse to be lulled to sleep by the enticements of sin. Let us live vigilantly in truth and righteousness, abstaining from everything that intoxicates the mind and soul. Sons of light are sober, diligently living with self-control and not indulging the flesh with sin. That is why sons of light are ready for the Lord’s return. Walk in the light of truth, not in the darkness of sin (1 Jno. 1:5-10). Be ready of His return.
21 I will praise You, for You have answered me, and have become my salvation. 22 The stone which the builders rejected has become the chief cornerstone. 23 This was the Lord’s doing; It is marvelous in our eyes. 24 This is the day the Lord has made; We will rejoice and be glad in it. (Psalm 118:21–24, NKJV)
We often hear verse 24 quoted and applied to the the first day of the week, the Lord’s day of worship. Without question, the Lord set the first day for assembled worship (Acts 20:7). Yet, the thanksgiving of this passage transcends the day of our weekly assemblies. It speaks of a day that evokes rejoicing and praise every day, including the first day of the week. “We will rejoice and be glad” in the day of God’s marvelous work of salvation, that He accomplished when He set Christ as the chief cornerstone of His temple, the church. The great day of Jesus Christ’s resurrection declared Him to be the Son of God, the very truth upon which He built His church (Romans 1:4; Matthew 16:18). His ascension, and exaltation at God’s right hand, declares the power to save us is in Him, and Him alone (Acts 2:32-36; 4:10-12). God made the day of salvation. It is accomplished in Jesus Christ. That day is marvelous in our eyes. Let us rejoice, and be glad in the day “the Lord has made.”
