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).
